"A horizontal loop of wire has a magnetic field passing upward through the plane of the loop. If this magnetic field increases with time, is the direction of the induced current clockwise or counterclockwise (viewed from above) as predicted by Lenz's law?

Anticlockwise direction

Explanation:

According to Lenz law, the induced current acts in a direction that opposes the change of flux producing it.

The loop is horizontal, and the magnetic flux is acting upward from the horizontal plane. This means that a Noth pole induced magnet has to be produced to counter this effect.

Anticlockwise flow of induced current produces a Noth seeking magnet while the reverse is true for a clockwise flow.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

what is the actual question though?
