Right Hand Rules

Front

What is the Right Hand Rule?

Back

A mnemonic used to determine the direction of the magnetic field, current, or force in electromagnetism.

Front

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

Back

Point your thumb in the direction of the current; your fingers curl in the direction of the magnetic field.

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.

Front

What happens to the magnetic field when the current direction is reversed?

Back

The direction of the magnetic field also reverses.

Front

What is the relationship between current and magnetic field strength?

Back

The strength of the magnetic field is directly proportional to the amount of current flowing through the wire.

Front

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

Back

Using the Right Hand Rule, if the current flows upwards, the magnetic field direction is into the page above the wire.

Front

What is electron flow in a circuit?

Back

Electrons flow from the negative terminal to the positive terminal, opposite to conventional current.

Front

What is a dipole magnet?

Back

A magnet that has both a north and a south pole, such as a bar magnet.

Front

What occurs when a permanent magnet is cut in half?

Back

It results in two dipole magnets, each with a north and south pole.

Front

What is the significance of the right side of a wire in terms of charge?

Back

The right side of the wire is considered positive when current flows from left to right.
