Previous Next Magnetic Field from a Coil # 5H25.10
Description: A bar magnet is placed on a rotating stand near a coil. A DC power supply is then switched on, creating a current in the coil and therefore a magnetic field. The bar magnet then rotates so that its magnetic field is aligned with the coil's magnetic field. Parts: Coil, DC power supply, bar magnet, rotating stand Purchased/Built: built Setup Time: 5 minutes Quant. in Demo Room: 2 Demo References The Video Encyclopedia of Physics Demonstrations Disc 19-10 A suspended solenoid reacts with a bar magnet only when the current is on. Freier and Anderson Ei-7 A bar magnet is mounted in a large flat coil. Sutton E-124 The deflection of a compass needle in the center of a large coil placed in the plane of the magnetic meridian is proportional to the tangent of the current. Freier and Anderson Er-1 A solenoid on a pivot and a magnet on a pivot interact.
