What happens if you hold the south pole of one magnet close to the north pole of another magnet?
They will attract each other
They will repel each other
They will grow very hot
Nothing will happen
1) A wire carries a current, creating a magnetic field around itself as shown. The current in the wire is:
A. Directed to the right
A. Directed to the left
A. Equal to the magnetic field
In the same direction as the magnetic field
Solenoid #1 has a length L, cross-sectional area A, and N turns. Solenoid #2 has a length 2L, cross-sectional area 2A, and 2N turns. Which solenoid has the greater magnetic field at its center when equal currents are going through them?
#1
#2
Both have the same magnetic field.
Since it depends on the values of A and L, none of the above are correct
Compared to the magnetic field in coil A, the magnetic field in coil B is --- as big.
