Understanding the Corner Right Hand Rule

What is the primary purpose of the corner right hand rule?

• To calculate the speed of a moving charge

• To find the magnitude of a current

• To measure the strength of a magnetic field

• To determine the direction of force on a moving particle or current-carrying wire

When using the corner right hand rule, which finger represents the direction of the magnetic field?

• Index finger

• Ring finger

• Middle finger

• Thumb

What happens to a charge when it enters a magnetic field?

• It moves in a circular motion

• It accelerates in a straight line

• It moves randomly

• It stops moving

In the context of the corner right hand rule, what does a dot symbol represent?

• A magnetic field going into the page

• A current going into the page

• A magnetic field coming out of the page

• A current coming out of the page

How can the corner right hand rule be adapted for negative charges?

• By using the left hand instead

• By reversing the direction of the thumb

• By ignoring the magnetic field direction

• By using the middle finger for velocity

What is the direction of the force on a current-carrying wire if the magnetic field is pointing into the page and the current is to the right?

• Downwards

• To the left

• Out of the page

• Upwards

If a positive charge is moving to the right and the magnetic field is pointing down, what is the direction of the force?

• Downwards

• Upwards

• To the left

• Out of the page

What does the middle finger represent in the corner right hand rule?

• Direction of the force

• Direction of the current

• Direction of the velocity

• Direction of the magnetic field

How can the right hand rule help determine the sign of a charge?

• By comparing the force direction with the expected direction for a positive charge

• By observing the magnetic field direction

• By measuring the speed of the charge

• By checking if the force direction matches the velocity

In a scenario where the magnetic field is out of the page and the current is upwards, what is the direction of the force on the wire?

• Downwards

• To the left

• Upwards

• To the right
