A group of pith balls with negative charges are suspended from a single point, causing them to repel each other and spread out in a symmetrical pattern. The closer the balls are to each other, the more they will repel due to the like charges.

The factors that affect the current in an electric circuit include the voltage of the power source, the resistance of the circuit components, and the arrangement of the circuit (series or parallel). Increasing voltage or decreasing resistance will result in higher current flow.

In the electrical circuit with a battery and a fan, the battery converts stored chemical energy into electrical energy, which is then transferred through the circuit to the fan motor. The fan motor then converts the electrical energy into mechanical energy to rotate the fan blades, resulting in the conversion of energy from chemical to electrical to mechanical forms.

To make an electromagnet, wrap a coil of wire around an iron core and connect the ends of the wire to a battery. When the current flows through the wire, it creates a magnetic field around the coil, magnetizing the iron core and turning it into an electromagnet.
