What must be true in order for magnetism to induce an electric current in a wire? there needs to be a switch in the circuit. there cannot be a switch in the circuit. the wire must be part of a closed circuit. the wire must be part of an open circuit. mark this and return save and exit

The correct " The wire must be part of a closed circuit."

The three conditions that must be met in odder to have a current flowing in a wire are : The wire has to be a conductor that is  connected in a closed circuit , and you must have an emf to drive the charges in a certain direction in the wire.  A magnet that provides a changing flux will induce an emf that drives current.  When the magnet produces this emf, a current will only flow though the conducting wire if and only if the wire s part of a closed circuit.

Clearly, the correct answer is " The wire must be part of a closed circuit."

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
