Aflat circular loop of wire of radius 0.50 m that is carrying a 2.0-a current is in a uniform magnetic field of 0.30 t. what is the magnitude of the magnetic torque on the loop when the plane of its area is perpendicular to the magnetic field?

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.

explanation:

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
