The magnetic field around the coil runs very well and If there is no circuit resistance what about emf and Voltage are:
- The superconducting magnet is an electric magnet made of superconducting wire coils.
- They should be cooled to cryogenic temperatures during operation.
- In its superconducting mode the wire is resistant to electricity and therefore can conduct larger electrical currents than conventional wires, creating strong magnetic fields.
- According to the law of Lenz, this emf contradicts the current change.
- Therefore, the applied voltage should overcome this rear emf only, because there is no resistance in the circuit.
- Therefore, the applied voltage and rear emf should be equal and opposite to keep the current flowing in the circuit.
