WebThe magnets with the best performances are rare earth permanent magnets, especially the neodymium iron boron (NdFeB) type, which produce the strongest available magnetic field. 11.4 . Schematic of a linear electromagnetic generator: a permanent magnet suspended on elastic springs moves through a conductive coil. WebAs the magnet approaches the coil, it causes the left-pointing magnetic field in the coil to increase. Lenz’s law tells us that the emf induced in the coil will drive a current in the direction that creates a magnetic field pointing to the right. This will counter the increasing magnetic flux pointing to the left due to the magnet. slowest new cars
