Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor.

True

The direction of the force on doubly ionized helium atoms (alpha particles) moving at right angles to a magnetic field is opposite to the direction of the force given by the third right-hand rule.

False

1 answer

An increase in current produces a stronger magnetic field.
I don't know what the third right hand rule is.
