True
The electromagnet will become stronger if we add more coils because there are more field lines in a loop then there is in a straight piece of wire. In a solenoid there are a lot of loops and they are concentrated in the middle, as more loops are added the field lines get larger, therefore making the electromagnet stronger.
AN OBJECT FLOAT BECAUSE OF ITS LOW CAPACITY AND SINKS BECAUSE OF ITS HIGH CAPACITY
Distance between the focal point and the center of the lens
