*** TRUE OR FALSE: ANSWER ALL QUESTIONS***

1. A changing magnetic field can induce an emf (an emf is like a battery voltage which can power a circuit).

2. An emf (and therefore a current as well) can be induced in various process that involve a change in a magnetic flux.

3. When a magnetic bar is moving toward a loop of wire, current will be induced in the wire.

4.  When a magnetic bar is inside a loop of wire without motion, current will be induced in the wire.

5. When a magnetic bar is leaving a loop of wire, no current will be induced in the wire.

Explanation / Answer

1) false ( change in flux creates emf not field)

2) true

3) true ( since flux is changing)

4) false ( no change in flux ao no currwnt)

5) false( flux is changing emf will induce
