Many of the diagrams given in Fig. show magnetic field lines (thick lines in the figure) wrongly. Point out what is wrong with them. Some of them may describe electrostatic field lines correctly. Point out which ones.

Which of the following curves represent electrostatic field lines correctly?

Point out the correct direction of magnetic field in the given figures.

Point out the mistakes in the representations of the electrostatic fields given below.

Which of the following magnetic field (static) lines are correctly represented

The diagram below shows the magnetic field lines of earth in a limited space. The field lines are parallel and equidistant. Are the magnetic field lines uniform or non-uniform?

The figure shows some of the electric field lines corresponding to an electric field. The figure suggests

In the given figure find out magnetic field at point B (Given : I=2.5A, r=5cm)

The diagram below shows the magnetic field lines of earth in a limited space. The field lines are parallel and equidistant. Where is the position of the geographic north, A or B?

Figure shows some of the electric field lines correspoinding to an electric field. The figure suggests that

The following diagram shows two parallel straight conductors carrying same current.Copy the diagram and draw the pattern of the magnetic field lines around them showing their directions. What is the magnitude of magnetic field at a point 'X' which is equidistant from the conductors ? Given justification for your answer.
