A scientist runs an electric current along a wire. A magnetic compass is placed near the wire. The scientist observes that whenever 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 adds electric charge to the compass needle. The current increases the force of gravity on the compass needle.

The correct option is: The current creates a magnetic field around the wire

Explanation:

It is because the current flowing through the circuit creates a magnetic field around the wire.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
