Item Type:Left/Right Hand Rules Physic Instrument
Left-Hand Rule: Fix the coil on the bracket, connect 6V DC power supply, and connect a key and sliding varistor in the circuit. Use U085 shoe magnet to straddle the coil so that the pole between the two poles of the magnet is parallel to the plane of the coil. When the circuit is turned on, the coil rotates in a certain direction around the vertical axle. If the current direction or the direction of the magnetic field is changed, the direction of rotation of the coil is changed. The left-hand rule can be derived from the relationship between the directions of current action.
Right-Hand Rule:The coil is fixed on the bracket, and the two ends are connected to the ammeter to form a closed loop, and the U085 shoe magnet (the number of shoe magnets are juxtaposed) is inserted into the coil. Then, the coil is made to cut magnetic field lines in the magnetic field (the line swing angle 240. When the coil is inserted into the shoe magnet), the pointer deflection on the ammeter can be seen, indicating that an induced current is generated in the coil. If you change the direction of the coil movement or change the direction of the magnetic field, the direction of the galvanometer pointer also changes. By studying the relationship between the direction of the magnetic field, the direction of motion of the coil and the direction of the induced current, the right-hand rule can be derived.
