Which of the following describes what will happen if an iron core is inserted into a coil of wire? Answer A.The wire will have a larger magnetic field. B.The iron core will become magnetized. C.The wire will have a smaller magnetic field. D.The core will become smaller.
Weegy: Answer: B.The iron core will become magnetized. Magnetic Effect Of Current Or Electromagnetism The term "magnetic effect of current" means that "a current flowing in a wire produces a magnetic field around it". [ The magnetic effect of current was discovered by Oersted in 1820. Oersted found that a wire carrying a current was able to deflect a magnetic needle. Now, a magnetic needle can only be deflected by a magnetic field. Thus it was concluded that a current flowing in a wire always gives rise to a magnetic field round it. The magnetic effect of current is called electromagnetism which means that electricity produces magnetism. ] (More)
