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
Induce currents of varying magnitude by passing a magnet back and forth through different
coil wraps.
The number of coils in each set are, respectively, 10, 20, and 40. Observe the
current to double each time the number of coils is doubled.
NOTE: Make sure magnet is strongly magnetized and all connections are good
before using this equipment.
