Question

Acconding to,what lsw, an induced current acts to produce an opposing Dus a: Biot-Savart's o Lenz's a: Ampere's a Faraday's field that has A plane fies at comstant speed due North through the Earth's magnetic components that point both North and vertically down. In this situstion a: the left side of the plane hecomes positively charged. a: the right side of the plane becomes positively charged. a: the top of the plane becomes positively charged. the bottom ofthe plane becomes positively charged Problem 3 Consider a square loop, which is fully immersed in a constant magnetic field B. A motional" emf is induced in the loop, when the loop 0 rotates in the field along an axis perpendicular to the field D: is at rest, but the B field then suddenly changes. D: moves with constant velocity v perpendicular to B, and it leaves the field region O all of the above

Explanation / Answer

Problem 1

Lenz's Law

Lenz's law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in fluxand to exert a mechanical force opposing the motion.

Problem 3

Rotates in the field along an axis perpendicular to the field.
