A current in a secondary coil is induced only if:

Physics
1 answer:
forsale [732]3 years ago
8 0
B is the correct answer, only CHANGES in magnetic flux generate currents, steady magnetic fields do nothing, and as such steady currents will generate a steady magnetic field, but it will not change the magnetic field and will not generate more current in another coil, so A is incorrect. More turns would generate a stronger magnetic field, but not a changing magnetic field that could create currents in other coils, so D is wrong for the same reason as A. C is wrong because there is no picture to judge for one, but magnetic fields are always perpendicular to their mother currents, but it doesn't do anything that would generate a current in another coil.

SpyIntel [72]

1:1  is the ratio of the gravitational force that earth exerts on the sun in the winter and the force that it exerts in the summer because it is independent of temperature.

F=GMm/R²

Any action that aims to maintain, alter, or deform a body's motion is considered a force in mechanics. In his Principia Mathematica, Isaac Newton frequently used his three laws of motion to demonstrate the concept of force (1687).

According to Newton's first law, a body will remain in either its resting or equally moving condition along a straight path in the absence of an external force. The second law states that when an external force acts on a body, the body accelerates (changes velocity) in the direction of the force.
