To make an induced magnet stronger, you can focus on the following methods:
1. **Adding more primary coils**: Increasing the number of turns in the primary coil will enhance the magnetic field produced by the coil, which in turn can induce a stronger magnetism in the nearby ferromagnetic material.
2. **Increasing the current in the primary coils**: If you can increase the current flowing through the primary coil, this will also strengthen the magnetic field generated, leading to a stronger induced magnet.
3. **Using a core material with a higher magnetic permeability**: Utilizing a ferromagnetic material that has a higher magnetic permeability as the core can significantly enhance the strength of the induced magnet.
4. **Tuning the frequency**: If applicable, optimizing the frequency of the alternating current (if inductive coupling is used) can also have an effect on the effectiveness of induction.
Thus, the correct methods from your options would be "adding more primary coils” to increase the strength of the induced magnet.
