Years spent building an axial flux permanent magnet generator gave him the perfect foundation for a new challenge. Cold water needed reliable heating off the grid, and fuel or grid power carried too many hassles. He turned those existing rotors into the heart of a device that creates heat through nothing more than motion and magnetic fields.<\/p>\n<p><span id=\"more-242171\"\/><br \/><iframe title=\"I Built a Magnetic Induction Water Heater- HUGE Potential\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/_RZX3Z7QB9U?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><noscript><iframe title=\"I Built a Magnetic Induction Water Heater- HUGE Potential\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/_RZX3Z7QB9U?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/noscript><br \/>\nPermanent magnets use two rotors to move past a flat stator made completely of copper tubing. The tube winds itself into a tight spiral disc, and each link is soldered until the entire coil creates a full electrical conductor. As the magnets pass past, some water flows through the hollow tube. Eddy currents begin to spin inside the copper tubing, releasing heat that simply warms the metal up. This heat is subsequently transferred directly into the water, leaving very little waste.<\/p>\n<div class=\"aawp\">\n<div class=\"aawp-product aawp-product--horizontal aawp-product--ribbon aawp-product--sale\" data-aawp-product-asin=\"B082TMBYR6\" data-aawp-product-id=\"230155\" data-aawp-tracking-id=\"tec02e-20\" data-aawp-product-title=\"Jackery Portable Power Station Explorer 300 292Wh Backup LiFePO4 Battery Solar Generator for Outdoors Camping Travel Hunting Blackout  Solar Panel Optional\">\n<p>    <span class=\"aawp-product__ribbon aawp-product__ribbon--sale\">Sale<\/span><\/p>\n<div class=\"aawp-product__thumb\">\n<p>            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41Dvgs93gBL._SL160_.jpg\" alt=\"Jackery Portable Power Station Explorer 300, 292Wh Backup LiFePO4 Battery, Solar Generator for Outdoors...\"\/><\/p><\/div>\n<div class=\"aawp-product__content\">\n<p>            Jackery Portable Power Station Explorer 300, 292Wh Backup LiFePO4 Battery, Solar Generator for Outdoors&#8230;        <\/p>\n<div class=\"aawp-product__description\">\n<ul>\n<li>SPEED UP YOUR RECHARGEABILITY: It takes only 2 hours to recharge 80% battery of the power station through the wall outlet and 60W PD USB-C port&#8230;<\/li>\n<li>SAFE &amp; STEADY POWER SUPPLY: Armed with a 293Wh lithium-ion battery pack, the Explorer 300 features 2 Pure Sine Wave AC outlets that deliver stable and&#8230;<\/li>\n<li>POWER YOUR EXPECTATIONS: Featuring 2* AC outlet, 1* PD 60W USB-C port (input\/output supported) , 1* fast charge 3.0 port, 1*USB-A port and 1* DC car&#8230;<\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<p>\n<img decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/05\/02104654\/magnetic-induction-water-heater-project-1.jpg\" alt=\"Magnetic Induction Water Heater Project\" width=\"1280\" height=\"720\"\/><br \/>\nBuilding this device begins with a robust jig made of square steel bar. Welding frames hold the pieces in place, ensuring that they are perfectly aligned before any tubing hits the jig. You take lengthy lengths of 8mm copper tube and wrap them around the jig uniformly and without gaps until a complete disc appears. The clamps hold the coil firm while it is soldered, and then you rinse it all off with warm water to remove the flux residue. Once the stator is constructed, just slot it into a square outer frame, which is pounded to ensure that it is perfectly distanced from the rotors. Then you slap bearings and lock nuts in to ensure that everything flows smoothly between the two magnetic surfaces.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/05\/02104703\/magnetic-induction-water-heater-project-2.jpg\" alt=\"Magnetic Induction Water Heater Project\" width=\"1280\" height=\"720\"\/><br \/>A small submersible pump moves water through the system at a rate of approximately 600 liters per hour while utilizing only 10 watts. You simply connect the inlet and output with some flexible silicone tubing, which adds no further resistance or leaks. Everything just mounts onto a simple small base that keeps the drill or turbine drive perfectly aligned.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/05\/02104709\/magnetic-induction-water-heater-project-3.jpg\" alt=\"Magnetic Induction Water Heater Project\" width=\"1280\" height=\"720\"\/><br \/>First time out, he used a corded drill to get the rotors spinning at roughly 400 revolutions per minute, starting with 1.5 liters of water at a frigid 7.9 degrees Celsius in a well-insulated bucket. After three minutes, the temperature had risen to 24.4 degrees Celsius, with water pouring out at 28.4 degrees. Simple calculation revealed that we were generating 575 watts of heat in that time, and the speed of the item is what truly important here, as output grows with the square of the rotational rate. If you double the rpm, the power quadruples, and if you push it to 2000 revolutions per minute, you may have 14.5kW of continuous heat.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/05\/02104714\/magnetic-induction-water-heater-project-4.jpg\" alt=\"Magnetic Induction Water Heater Project\" width=\"1280\" height=\"720\"\/><br \/>The copper temperature remained nearly constant with the water temperature throughout the test, demonstrating that heat is efficiently transferred from the metal to the liquid, but the drill motor eventually became too hot to continue, while the heater barely batted an eye, and the water continued to flow and warm up until the end, and he did it all without the use of any fancy storage tank.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/05\/02104720\/magnetic-induction-water-heater-project-5.jpg\" alt=\"Magnetic Induction Water Heater Project\" width=\"1280\" height=\"720\"\/><br \/>This thing\u2019s direct mechanical drive makes it ideal for off-grid use. You can get a wind turbine or a tiny hydropower wheel to spin its rotors without first converting the motion into energy and then back again. The heat begins as soon as you start spinning the item and continues until it stops turning. You don\u2019t have to bother about combustion chamber vents or fuel tank storage, and the heating element will not burn out on you. It just takes all of that motion and converts it into hot water on demand.<br \/><span>[Source]<\/span><\/p>\n<\/p><\/div>\n<p> Spinning Magnets Deliver Hot Water Without Fuel or Electricity<br \/>\n<br \/>#Spinning #Magnets #Deliver #Hot #Water #Fuel #Electricity<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Greenhill Forge runs a rural workshop focused on hands-on projects for smallholding life.
