A bar magnet is rotated near a coil as shown below

Which of the following statement is correct for given situation?

1. Induced current flows in only one direction.
2. Strength of induced emf increases as the rotation speed is decreased
3. The strength of induced emf is affected due to coil resistance.
4. The direction of induced current changes alternatively.

Which of the following corresponds to Joule's law of heating?

1. I²R
2. I²Rt
3. V²Rt
4. IR²t

Assertion: Current is the rate of flow of charge.

Reason: Electric current will not flow between two charged bodies when connected, if they are at the same potential

1. Both Assertion and Reason are true.
2. Both Assertion and Reason are false.
3. Assertion is false but Reason is true.
4. Assertion is true but Reason is false
