Reading Quiz: Inductance and Magnetic Flux
The great British physicist Michael Faraday discovered magnetic induction about 150 years ago. How does an
differ from currents we’ve seen in circuits so far?
A circuit contains a coil of wire and an ammeter to measure current in the circuit. A bar magnet is inserted into
the coil and removed. When is a current induced in the circuit? Circle all that apply.
As the magnet is inserted into the coil of wire
While the magnet is at rest in the coil of wire
As the magnet is removed from the coil of wire
can be described as:
