. A cyclist rides around a circular track (R == 100 ft) such that the point of contact of the wheel on the track moves at a constant speed of 30 ft/sec. He banks his bicycle at 15° with the vertical. Find the acceleration of a tack in the tire (1.25 ft radius) as it passes through the h

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.
