To increase the magnitude of the magnetic field produced when a current is passed through a coil whose length is much greater than its radius, one can: - Decrease the diameter of the wire in the coil. - Increase the magnitude of the current. - Stretch the coil along its axis. - Increase the diameter of the wire in the coil.

4-5. How can the magnetic flux through a coil of wire be increased? Select two answers: A. Increase the cross-sectional area of the loop. B. Increase the magnitude of the magnetic field that passes through the loop. C. Increase the magnitude of the magnetic field that passes outside the loop. D. Orient the loop so its normal vector is perpendicular to the external magnetic field direction.
Imagine bringing a bar magnet near a coil of wire and inducing a brief current in that coil. How could you increase the amount of current induced in the coil? Check All That Apply Move that magnet towards the coil with a greater speed. Increase the number of turns of wire in the coil. Increase the magnetic field strength. Increase the resistance of the coil. Decrease the number of loops of wire in the coil.
