Refer to the image below and state how the magnetic field pattern indicates regions wherethe magnetic field is stronger outside the magnet? What happens to the magnetic fieldwhen the current in the circuit is reversed?

​the diagram below shows a current carrying wire placed inside a magnetic coil.State the difference it would make if the wire is replaced with a coil with more turns.Secondly the direction of current is reversed and the poles of the magnets are also reversed.Describe your answer in 25 to 35 words.B

The magnetic field lines due to a straight current carrying wire are shown in figure. The direction of current in wire is upwards. The magnetic field is weakest at point

A coil of wire is carrying an electric current. How will the magnetic field of the coil be affected if an iron rod is placed in its center ?A The field will be cancelled out. B The strength of the field will increase. C The strength of the field will decrease. D The direction of the field will reverse.

What happens to the current flowing through a circuit as resistance increases?A It increases.B It decreases.C It stays the same.D It reverses direction.
