learning task 3: complete the table with the information gathered from the ray diagramming task you have completed

not too sure thinking all accelerations are pointed down

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.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
