The magnetic field of a long, straight, and closely-wound solenoid, inside the solenoid at a point near the center, is 0.920 T. What is the magnitude of the magnetic field at this point if the current in the solenoid is increased by a factor of 2.50?

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

prolly a beacuse the momentuem the car has increases while going down hill

iron would move it is magnetic there is a mag field around the current in the wire
