TRUE OR FALSE A stationary charged particle can be affected by an external magnetic field, via magnetic force.

Expert Solution

Ans) The statement is FALSE.

Lorentz Force Law states that magnetic force on a charged particle in magnetic field is given by, F= q v x B

Where, v: velocity

B : magnetic field

q : charge on the particle

Letters in bold are vectors.

if velocity (v) =0, then F=0. Therefore, there is no magnetic force on stationary charges in a stationary/ constant magnetic field.

In case of a time varying magnetic field, the time varying magnetic field creates an electric field as per the relation. Then this electric field will exert an electric force on the charge and charge will experience net force. However, the magnetic force on the charge is still zero. Therefore, a stationary charged particle cannot be affected by external magnetic force via magnetic force.

A charged particle moving through a magnetic field at right angles to the field with a speed of 35.1 m/s experiences a magnetic force of 7.56x10-4 N. Determine the magnetic force on an identical particle when it travels through the same magnetic field with a speed of 8.7 m/s at an angle of 44° relative to the magnetic field. Express your answer in microNewtons.

3. Perturbations due to external magnetic field. A zero spin particle in a spherically symmetric potential has energy levels given by Enl. What are the perturbations of the energy levels and the wave function to leading order in perturbation theory due to the presence of a homogeneous external magnetic field of magnitude B?

When a charged particle moves in an electric field, the field performs work on the particle. Thus, the energy of the field decreases, turning into kinetic energy of the particle. Does the magnetic field of a permanent magnetic similarly lose energy and perform work when moving a conductor with a current?

The potential energy of a magnetic moment in an external magnetic field is U = -...

The potential energy of a magnetic moment in an external magnetic field is U = - ??B. U is smallest when B is parallel to ? and largest when it is antiparallel. Since the magnetic moment of the electron is directed opposite to its spin (because it has a negative charge), the electron’s energy is highest when the spin is parallel to B. The two possible energy states for the electron are the spin up state (ms = 1212) and...

Which of the following statements are true? True False Magnetic field lines always start at a North and end at a South pole. True False When placing a dipole magnet into a magnetic field, it will be accelerated perpendicular to the field lines. True False The force on a moving charge is perpendicular to both the field and its velocity. True False The larger the charge of a moving particle, the more it will accelerate inside of a magnetic field.

True or False The magnetic field at a radial distance R from a current element i dl is a maximum when the current element direction is at right angles to the radial line. Induced electric field lines are continuous, i.e. having no beginning or ending points. An arbitary shaped Amperian loop through which no currents pass may itself pass through a magnetic field. Induced electric field lines have a beginning and end point. The negative sign in Faraday's Law (Lenz's...
