Specifications Material Magnet plasticSize 12 x 9cmScope Of Application Wire magnetic field physics teaching instrument Features Good teaching tools Has a good experimental display effect How To Use Type A Connect the wires screw the two suspension rods into the holes with the soldering holes and hang the square coil One end of the U shaped magnet is placed on the bottom plate and the other end is placed in the square coil hole Inside press the Type A switch slide the varistor and 2A power supply self prepared voltage DC4 6V Observe that the square coil composed of the wire and the suspension column rotates at an angle in a certain direction observes the change of the direction of movement of the conductive tube in the magnetic field and explores its law What is the change in the magnitude of the current Experiments show that the energized wire is subjected to the force in the magnetic field and the direction of the force is related to the direction of the current the direction of the magnetic induction line and the magnitude of the current When the direction of the current or the direction of the magnetic induction line becomes opposite the direction in which the energized wires are subjected to force also becomes opposite Type B Connect the wire sliding varistor and single pole switch to the DC output of the 2A low voltage power supply Adjust the power supply voltage to 6 8V Place the hollow copper tube on the conductor rolling guide f
