Marque a seleção "Mostrar medidor de campo". Movimente o medidor de campo. O que você observa em relação ao campo magnético , quando o medidor se aproxima do imã?

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

your answer is, orbit around the nucleus

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.
