Draw a figure of current-carrying solenoid and show magnetic field lines inside and outside it. Compare the pattern of the field with the magnetic field around a bar magnet.

Important Questions on Magnetic Effects of Electric Current


An particle enters a uniform magnetic field at right angles to it as shown in figure. Stating the relevant principle, explains in which direction will this - particle move.

State whether an alpha particle will experience any force in a magnetic field if (alpha particles are positively charged particles) it is placed in the field at rest. Justify your answer.

State whether an alpha particle will experience any force in a magnetic field if (alpha particles are positively charged particles) it moves in a magnetic field parallel to field lines. Justify your answer.

State whether an alpha particle will experience any force in a magnetic field if (alpha particles are positively charged particles) it moves in the magnetic field perpendicular to field lines. Justify your answer.

State whether an alpha particle will experience any force in a magnetic field if (alpha particles are positively charged particles) it is placed at rest. Justify your answer.

State whether an alpha particle will experience any force in a magnetic field if (alpha particles are positively charged particles) it moves parallel to the magnetic field lines. Justify your answer.
