Frequency does not have a direct relationship with the strength of an electromagnet, which typically operates on DC current. Electromagnets can achieve high magnetic fields, such as 45000 gauss, but this strength is primarily determined by the current and the number of loops in the coil. The formula provided indicates that the magnetic field strength (B) is influenced by the current (I), the number of loops (n), and the radius (r) of the coil. While AC can be used, it must be converted to DC for effective electromagnet operation. Understanding these principles is crucial for applications involving electromagnets and their magnetic fields.
