Respuesta :
increase the strength of the magnetic field when current flows through the circuit
She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
halfway between the like poles of two magnets, because the field lines bend away and do not enter this area
A generator converts kinetic energy to electrical energy, and a motor converts electrical energy to kinetic energy.
A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.
Liang most likely trying to increase the strength of the magnetic field.
What is magnetic field?
The magnetic field is the region of space where a charged object experiences magnetic force when it is moving.
When current flows through the circuit, the coil gets magnetized. In an electrical circuit , the magnetic field of a straight wire has less magnetic field strength than that of coiled wire.
She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
Thus, Liang most likely trying to increase the strength of the magnetic field.
