Looking at the solenoid below, identify your north and south end by wrting N and S on the appropriate side of the drawing. Then draw the magnetic field lines produced by this solenoid. Make sure to show the direction of your field lines by including arrow heads.

Can someone explain this problem step by step? please

In a Curie-type paramagnet, all the ions with magnetic moments contribute to the total susceptibility, but in a metal, only very few of the free electrons contribute to Pauli paramagnetism. Why?

to the primary side. Question # 3 The coils of the magnetic circuit shown in the figure are connected in series. They are wound with equa turns of 100 turns each. The dimensions are: Cross-section area of A and B legs 7 cm2 Cross-section area of C leg 14 cm? Length of A path is 17 cm Length of B path is 17 cm Length of C path is 5.5 cm Length of the air gap is 0.4 cm The material has a constant relative permeability of H of 2800. Neglect the fringing effect and leakage flux. 00 %3D Calculate the current required to produce a flux density of 1.2 T in the air gap.

Please i need help with this problem Can you help me?

A current path of the shape shown in the figure produces a magnetic field at P, the center of the arc. If the arc subtends an angle of 30 ° and the radius of the arc is 0.600 m, what are the magnitude and direction of the field produced at P if the currents are 3A?
