Acharge q with mass m has a velocity far away. a small metallic loop of area a and resistance r is fixed and oriented such, that it and the vector 7 are in the same plane. the impact parameter of the charge with respect to the loop is h. assuming that r, there is not gravity and air resistance, find the velocity (magnitude and direction) of the charge after a very long time

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

answer is slate

hope this

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
