Using the motor principle explain why a motor is rotating in the direction indicated.

I seriuosly have no idea, please help explain this theory to me.

To help you answer that question, I'd need a figure that shows what kind of motor (or magnet) it is, the direction of the external magnetic field, whether the field is changing, and which direction the motor is turning.

You have provided none of this information.

it's an electric motor. the current flow is flowing north. There is a north magnet on the right and a south magnet on the left of the motor. Sorry I don't know what the direction of the external magnetic field is...the motor is turning clockwise.

sorry, the north magnet is actaully on the LEFT and the south magnet is on the RIGHT

To explain why the motor is rotating, we need to apply the motor principle, also known as Flemming's left-hand rule.

Flemming's left-hand rule states that when a current-carrying conductor is placed in a magnetic field, a force will act on the conductor, causing it to move in a particular direction.

In this case, assuming the current flow is from left to right (north to south), and the north magnet is on the right and the south magnet is on the left, we can follow these steps to determine the motor's rotation direction:

1. Identify the current direction: The current flow is from north to south, or left to right.

2. Identify the magnetic field direction: The north magnet is on the right, and the south magnet is on the left. In the absence of information about the external magnetic field, we can assume it is from north to south.

3. Apply Flemming's left-hand rule: Place your left hand with the thumb pointing in the direction of the current flow (left to right) and the fingers pointing in the direction of the magnetic field (north to south in this case). The force acting on the conductor will be perpendicular to both the current direction (thumb) and the magnetic field direction (fingers).

Since the force is acting towards you, the conductor (motor) will experience a clockwise torque, causing it to rotate clockwise.

Remember, this explanation assumes a simple scenario with a conventional electric motor. The direction of rotation can be affected by factors such as the shape and arrangement of the motor's components, the specific wiring, and the precise orientation and strength of the magnetic field.
