What are the consequences if magnetic effect cannot be caused by electric
current ?
Answers
Answer:
Magnetic Field Due to Flow of Current through a Circular Loop. The magnetic field produced in a circular current carrying conductor is the same as that of the magnetic field due to a straight current-carrying conductor and the current-carrying circular loop will behave like a magnet.
Answer:
Magnetic Effect of Electric Current – A magnetic field is a force field that is created by magnetic dipoles and moving electric charges, and it exerts a force on other nearby moving charges and magnetic dipoles.
The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.
