Which property of the magnetic field is not correct?

Outside the magnet, magnetic field lines go from south to north pole of the magnet is not the correct statement regarding magnetic field. Explanation: The two magnetic field lines never intersect each other.

Which property of the magnetic field lines is wrong?

Solution : (a) Wrong, because magnetic lines of force never emanate from a single point as shown. The field lines shown represent electric field of a single positive charge.

Which of the following is correct about magnetic field?

Which of the following is correct about magnetic field lines? Notes: The magnetic field lines are closed curves. The relative strength of the magnetic field is shown by the degree of closeness of the field lines. This question is part of 20000+ General Studies MCQ Series Course on GKToday Android app.

Can you direct a magnetic field?

Yes, it is possible to guide magnetic field lines using a shaped magnetic material. Just as field lines concentrate when entering the south pole of a magnet from a large area, an external magnetic field can be “gathered” using, for example, a cone-shaped piece of iron.

At which point is the magnetic field the strongest?

The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

What are the properties of magnetic field lines?

Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:

  • The field is tangent to the magnetic field line.
  • Field strength is proportional to the line density.
  • Field lines cannot cross.
  • Field lines are continuous loops.

How can a magnetic field be produced?

Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.

Which of the following is correct about magnetic monopole?

Magnetic monopole does not exist. Magnetic monopole have constant value of monopole momentum. The monopole momentum increase due to increase at its distance from the field.

Do magnetic forces follow Newton’s third law?

The magnetic force does not have the property of reciprocity. To put it another way, the forces do not obey Newton’s third law, which means that this “law” is not fundamental but rather a relationship that applies to electric and gravitational interactions but not to all types of interaction.

Which is the direction of magnetic field inside a magnet?

The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet.

What blocks magnetic fields?

The advantage of absorbing a magnetic field is that it won’t bounce around in another direction. What’s generally required is a ferromagnetic material containing iron, nickel, or cobalt. The thicker this material is, the better it will perform at absorbing a magnetic field.

Does aluminum block magnetic fields?

Most conductive materials such as aluminum, copper and mild steel provide substantial electric shielding. … Unfortunately, aluminum foil is extremely inadequate against low frequency magnetic fields, where thick steel or highly permeable ferrite material provides more adequate shielding.30 мая 2017 г.

How do you manipulate magnetic fields?

Typically, there exist three ways to manipulate micro- and nano-objects placed in a magnetic field: the use of (1) a gradient magnetic force, (2) a magnetic interaction force between objects, and (3) a magnetic torque. Note that the magnetic interaction force is actually one special type of gradient magnetic force.

At which of the four points shown is the strength of the magnetic field greatest?

At which point is the magnetic field strength greatest? Answer: (B) has the greatest magnetic field strength because it is located at the highest density of magnetic field lines.

What is the weakest part of a magnetic field?

The magnetic field is weakest along the surface in the middle of the side of the magnet. This is a close-up of the field at the North pole.

Where is the strength of magnetic field?

A vector quantity indicating the ability of a magnetic field to exert a force on moving electric charges. It is equal to the magnetic flux density divided by the magnetic permeability of the space where the field exists. It is measured in amperes per meter.
