Question

A magnetic field near the floor points up and is increasing. Looking down at the floor, does the non-Coulomb electric field clockwise or counter clockwise? A magnetic field near the ceiling points down and is decreasing. Looking up at the ceiling, does the non-Coulomb electric field curl clockwise or counter clockwise?

Short answer

The floor and ceiling both are counter clockwise.

Step-by-step solution

Given Information.

A magnetic field near the floor points up and is increasing.

Definition/ Concept.

The magnetic field's direction and the electric field's direction are opposite each other. The non-coulomb electric field curls in a clockwise manner as the magnetic field is increased downward toward the floor.

Find floor is clockwise or counter clock wise.

The figure will be:

The facts are:

(a). The magnetic field, B is pointing upwards.

(b). The magnetic field is increasing. Therefore, the quantity $dB/dt$is pointing in the same direction as B.

So, by using the right hand thumb rule on $-dB/dt$, this can be observed that the direction of $E_{NC}$is counter clockwise.

Therefore, the floor is counter clockwise.

Find ceiling is curl clockwise or counter clock wise.

The figure will be:

The facts are:

(a). The magnetic field, B is pointing upwards.

(b). The magnetic field is decreasing. Therefore, the quantity $dB/dt$is pointing in the opposite direction as B.

So, by using the right hand thumb rule on $-dB/dt$, this can be observed that the direction of $E_{NC}$is counter clockwise.

Therefore, the ceiling is counter clockwise.
