## How do you determine if current is clockwise or counterclockwise?

It is “clockwise” when you look at your hand thumb-on, or when you look at the change pointing towards you. This means that if a current follows that curling, it goes to a higher voltage; or if it opposes that curling, it goes to a lower voltage. This same “reverse” rule can also be phrased as Lenz’s law.

## Which law determine the direction of induced current in a coil?

When a magnetic field is changing through a coil, a current is generated in the coil which is known as induced current. The direction of this induced current is given by Lenz law.

## What is the direction of the induced current in the circular loop?

The direction of the induced current in the circular loop is counterclockwise. In c, the current is constant implying that there is no change in flux. Therefore, the induced current in the circular loop is zero.

## Why is the induced current clockwise?

a. Clockwise. Since the ‘dot’ field is increasing hence the induced magnetic field is’cross’,i.e. into the page and by the right-hand rule the induced current is clockwise.

## How can the polarity or direction of an induced current be reversed?

The direction of the induced voltage is reversed when the magnet is moved out of the coil again. It can also be reversed if the other pole of the magnet is moved into the coil.

## What are the methods to determine the direction of induced emf?

Stretch the forefinger, middle finger and the thumb of the right hand mutually perpendicular to each other. If the force finger points in the direction of the magnetic field, the thumb gives the direction of the motion of the conductor then the middle finger gives the direction of the induced current.
