Web6. Gauss’s Law allowed us to find the net electric field due to any. charge distribution by applying symmetry. 7. Ampere’s Law is a useful law that relates the net magnetic field. along a closed loop to the electric field current passing through the. loop. 8. All currents have to be steady and do not change with time. WebThe magnetic force produced by a solenoid can be defined using the Law of the Ampere: F = μ 0 n I Where n is the number of turns of the wire per unit length, I is the current flowing …

They are totally different.
WebThe magnetic field from the solenoid aligns the magnetic domains inside the iron along the same direction. This domain alignment then creates a permanent net magnetic field inside the iron which supplements the external mag field from the solenoid since they are both aligned in the same direction.
