Right Hand Rules

Front

What is the Right Hand Rule?

Back

A mnemonic used to determine the direction of the magnetic field in relation to the direction of current flow in a conductor.

Front

What does the thumb represent in the Right Hand Rule?

Back

The direction of the current (I) in the conductor.

Front

What does the index finger represent in the Right Hand Rule?

Back

The direction of the magnetic field (B) around the conductor.

Front

What does the middle finger represent in the Right Hand Rule?

Back

The direction of the force (F) experienced by a positive charge in 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 is the difference between conventional current and electron flow?

Back

Conventional current flows from positive to negative, while electron flow is from negative to positive.

Front

What is the significance of the south pole of a magnet?

Back

The south pole is the end of a magnet that is attracted to the Earth's magnetic north.

Front

How does the direction of current affect the magnetic field?

Back

Reversing the direction of current reverses the direction of the magnetic field.

Front

What is the first Right Hand Rule used for?

Back

To determine the direction of the magnetic field around a straight conductor.

Front

What is the second Right Hand Rule used for?

Back

To determine the direction of the force on a current-carrying conductor in a magnetic field.
