P4.2.3 - Electromagnetic Induction Flashcards
1
Q
How do you produce an induced potential difference?
A
By moving a conductor into a magnetic field
2
Q
Why is induced potential difference created?
A
The new conductor changes the magnetic field so that it cuts magnetic field lines
3
Q
What does the induced potential difference depend on?
A
The length of the wire in the field and the rate at which you cut field lines
4
Q
How can you increase the reading on a voltmeter?
A
Moving the wire faster
Using a stronger magnetic field
Using more wire
