Find the magnitude of the magnetic field these two segments

Question

Question -1:

A wire carrying a 26.0 current bends through a right angle. Consider two 2.00 segments of wire, each 3.00 from the bend.

Part A

Find the magnitude of the magnetic field these two segments produce at point, which is midway between them

Part B

Find the direction of the magnetic field at point.

Question -2:

In a region of space, a magnetic field points in the + x - direction (toward the right). Its magnitude varies with position according to the formula B_x = B_o ± bx, where a and b are positive constants, for x > 0. A flat coil of area A moves with uniform speed v from right to left with the plane of its area always perpendicular to this field.

Part A

What is the emf induced in this coil while it is to the right of the origin? Express your answer in terms of the given quantities.

Part B

As viewed from the origin, what is the direction (clockwise or counterclockwise) of the current induced in the coil?

Part C

If instead the coil moved from left to right, what would be the answer to part A? Express your answer in terms of the given quantities.

Part D

If instead the coil moved from left to right, what would be the answer to part B?
