How canthe knowledge of electric potential us understand the motion of electrically charged particles in electric circuits? answer in your notebookand on the whiteboard.

if you answer my question i will answer yours

a sonic boom is a loud boom that breaks the sound barrier

explanation:

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.
