A college student designed and constructed an electric generator in his physics class to investigate cause and effect connections about magnetism and electricity. When he first tested this generator, it only produced 50 amps. However, his goal was for this generator to induce 100 amps. What is one action that he could do to make this happen?

To increase the amperage output of the electric generator from 50 amps to 100 amps, the college student could take the following actions:

1. **Add an iron core**: By adding an iron core within the coils of the generator, the magnetic field strength would increase. This stronger magnetic field can induce a higher current in the coils, resulting in a higher amperage output.

2. **Move the magnet faster between the coils**: Increasing the speed at which the magnet moves between the coils can lead to a higher rate of change of magnetic flux. According to Faraday's law of electromagnetic induction, a faster movement of the magnet induces a higher electromotive force (emf) and consequently a higher current flow.

3. **Use an electromagnet**: Replacing the permanent magnet with an electromagnet can provide greater control over the magnetic field strength. By adjusting the current flowing through the electromagnet, the student can increase the magnetic field intensity, leading to a higher induced current in the generator coils.

By implementing these actions, the college student can enhance the efficiency of the electric generator and achieve his goal of generating 100 amps of current.
