RIght Hand Rule

Front

What is the Right Hand Rule?

Back

A mnemonic used to determine the direction of the magnetic force on a current-carrying conductor in a magnetic field.

Front

How do you apply the Right Hand Rule for a current-carrying wire?

Back

Point your thumb in the direction of the current (I), your fingers in the direction of the magnetic field (B), and your palm will face the direction of the magnetic force (F).

Front

What is the direction of the magnetic force if the current is moving into the page and the magnetic field is directed upwards?

Back

The magnetic force will be directed to the left.

Front

If the current is moving out of the page and the magnetic field is directed to the right, what is the direction of the magnetic force?

Back

The magnetic force will be directed upwards.

Front

What happens to the direction of the magnetic force if the current direction is reversed?

Back

The direction of the magnetic force will also reverse.

Front

What is the relationship between current, magnetic field, and magnetic force?

Back

The magnetic force on a current-carrying wire is given by F = I (L x B), where F is the force, I is the current, L is the length of the wire, and B is the magnetic field.

Front

What is the unit of magnetic field strength?

Back

Tesla (T).

Front

What is the formula to calculate the magnetic force on a wire?

Back

F = I * L * B * sin(θ), where θ is the angle between the wire and the magnetic field.

Front

What does it mean if the magnetic force is zero?

Back

It means that either the current is zero, the magnetic field is zero, or the angle between the wire and the magnetic field is 0° or 180°.

Front

What is the direction of the magnetic field around a straight current-carrying wire?

Back

The magnetic field forms concentric circles around the wire, with the direction determined by the Right Hand Rule.
