Anormal polarity magnet moves toward a stationary coil at 20 cm/s, and induces a maximum current of –8 ma. which scenarios would induce the same maximum current and the same current direction (–), if the distance between the two objects is the same? check all that apply. a stationary magnet and a coil rotating at 20 cm/s rather than moving both the magnet and the coil moving toward each other at 10 cm/s each a reversed polarity magnet moving toward a stationary coil at 10 cm/s a normal polarity magnet stationary with a coil approaching at 15 cm/s a reversed polarity magnet moving away from the coil at 20 cm/s

both the magnet and the coil moving toward each other at 10 cm/s each

Explanation:

Here we need to find a situation in which the direction of current will not change and also the magnitude will remain same

Now we know that due to relative motion of coil and magnet the magnetic flux linked with the coil will change and this will induce current in the coil.

Now if we do not change the polarity of magnet then the direction of current will remain the same and here if the relative motion of the coil and magnet is same then the magnitude of current will be same

SO as here in the situation it the relative velocity of coil with respect to magnet is same and there is no change in polarity of magnet then the magnitude of current as well as the direction will remain same always.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
