(5%) Problem 4: Consider a lightning bolt at the equator that carries 19500 A Randomized Variables I = 19500 A 50% Part (a) what is the magnitude of the magnetic force per meter (N/m) on the lightning bolt if it is perpendicular to the Earth's 3.00 x 10-5 T field?

Hi nts remaining: 2 Feedback: 2-deduction per feedback. 50% Part (b) What is the diction of the force if the current is straight up and the Earth's field direction is due north, parallel to the ground?Explanation / Answer
a) F = B I L
F / L = B I
= 3 * 10-5 * 19500
F / L = 0.585 N/m
b)magnetic field is parallel to north so palm points to left or west
direction of force is towards west
