SUMMARY
Building an AC electromagnet can interfere with nearby electrical devices, particularly at 50/60Hz frequencies, which can disrupt TV screens, computer monitors, and magnetic stripes on credit cards. For frequencies exceeding 100kHz, interference with AM radio reception becomes a concern. Understanding the impact of electromagnetic fields is crucial for anyone engaging in such projects.
