A scientist runs an electric current along a wire. A magnetic compass is placed near the wire. The scientist observes that whene
ver the current is turned on, the compass needle moves. Why does the compass needle move? Question 9 options: The current creates an electric field around the wire The current creates a magnetic field around the wire The current increases the force of gravity on the compass needle. The current adds electric charge to the compass needle.
The magnetic field causes deflection of the needle of a compass . The electric current causes a magnetic field around the wire due to which the compass needle moves.
<h3> what is a solenoid?</h3>
A solenoid is an electric current-conducting coil of wire. An electromagnet built with a wire helical coil is known as a solenoid.
A magnetic field is created when an electric current is sent through the coil. When an electric current runs through a solenoid. It creates a magnetic field.
