• up

• down

• left

• right

In which direction will the force act on this current-carrying wire?

• up

• down

• left

• right

What direction does the magnetic force act on this current-carrying wire?

• left

• right

• in

• out

The force on this current-carrying wire is upwards, what is the direction of the current in the wire?

• from X to Y

• from Y to X

A current-carrying wire has its (conventional) current flowing upwards. The wire is in a uniform magnetic field directed into the page. What direction is the force on the wire

• up

• down

• left

• right

A current-carrying wire has its (conventional) current flowing downwards. The wire is in a uniform magnetic field directed out of the page. What direction is the force on the wire?

• left

• right

• into the page

• out of the page

A current-carrying wire has its (conventional) current flowing into the page. The wire is in a uniform magnetic field directed to the right (always N to S). What direction is the force on the wire?
