A potential difference is generated when a wire experiences a in magnetic field.
|
Which of the following would generate a potential difference in a wire?
(the wire is within the magnetic field of a nearby magnet)
Moving either the wire or the magnet
Only moving the magnet
Only moving the wire
|
A wire moving up and down repeatedly perpendicular to a magnetic field will:
Not generate a potential difference
Generate a constant potential difference
Generate an alternating potential difference
|
A wire moving parallel to a magnetic field will:
Generate an alternating potential difference
Generate a constant potential difference
Not generate a potential difference
|
Name the three ways to increase the size of the potential difference generated in electromagnetic induction
|
constant / changing / voltage / current
- When a wire experiences a magnetic field, a potential difference will be induced across the wire.
- If the ends of the wire are connected to make a closed circuit, then a will flow around the circuit.
