Another thing...When does the wire/coil watever cuts the magnetic field..When it is vertical or horizontal ???
--- End quote ---
- When a current carrying wire / coil goes between the magnetic field.
- When a magnet is pushed in / out of the coil.
- When a wire goes across the magnetic field.
- When an electromagnet is placed right next to a solenoid, it only cuts the magnetic field at the instance when it is being switched on and off.
