A cat chases a mouse across a 1.1 m high table. The mouse steps out of the way, and
the cat slides off the table and strikes the floor
1.7 m from the edge of the table.
The acceleration of gravity is 9.81 m/s?.
What was the cat's speed when it slid off
the table?
Answer in units of m/s.

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.
