The direction of the magnetic field is determined by which of the following? a. energy of the current b. magnetic domain c. magnetic force d. direction of the current

C.magnetic force

Explanation:

A magnetic field is responsible for the magnetic forces acting on a moving charge, so we can say that the direction of the magnetic field is determined by the magnetic forces.  In the case of a conductor traversed by electric current and subjected to the presence of a magnetic field, we will also have the action of a magnetic force, since the current represents an orderly movement of electric charges.

An example of the application of magnetic force occurs in the TV tube, where a set of coils (artificial magnets), with their magnetic fields, enables the action of magnetic forces that deflect electron beams, causing them to traverse the entire screen. These electron beams sweep the phosphor-coated screen, line by line, from left to right and top to bottom, allowing the image to emerge.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

what is the question because that is not a question.
