Question

A 5.0 m portion of wire carries a current of 4.0 A from east to west. It experiences a magnetic field of 6.0 times 10 to the power of negative 4 end exponent T running from north to south. What is the magnitude and direction of the magnetic force on the wire?

1.2 times 10 to the power of negative 2 end exponent N upward
2.4 times 10 to the power of negative 2 end exponent N downward
2.4 times 10 to the power of negative 2 end exponent N upward
1.2 times 10 to the power of negative 2 end exponent N downward

Answer 1

A) 1.2 times 10 to the power of negative 2 end exponent N upward
