Induced Currents & Forces: Electromagnetic Induction
Induced Currents & Forces: Electromagnetic Induction
Purpose
To observe the dependence a solenoid's number of coils has on the current
generated by a nearby moving magnet.
Description
Compare the galvanometer readings (and direction of current flow) while moving a
magnet in and out of a solenoid. Two different solenoids, each with different
number of turns, are available.
NOTE: Make sure magnet is strongly magnetized and all connections are good
before using this equipment.
Equipment
Solenoid board and bar magnet
