Question

- Constants 1 Periodic Table Part B The force on a wire is a maximum of 4.00 x 10-2N when placed between the pole faces of a magnet. The current flows horizontally to the right and the magnetic field is vertical. The wire is observed to ump" toward the observer when the current is turned on. If the pole faces have a diameter of 12.0 cm, estimate the current in the wire if the field is 0.23 T Express your answer using two significant figures. Submit ? Part C lfthe wire is tipped so that it makes an angle of 18.0 ° with the horizontal, what force will it now feel? Submit Request Answer Provide Feedback Next >

Explanation / Answer

here,

force , F = 0.04 N

B)

diameter , d = 12 cm =0.12 m

radius ,r = 12 /2 = 6 cm = 0.06 m

magnetic feild , B = 0.23 T

F = B * I * L

0.04 = 0.23 * I * 0.12

I = 1.45 A

C)

theta = 18 degree

F = B * I * L * sin(theta)

0.04 = 0.23 * I * 0.12 * sin(18)

I = 4.7 A
