Question

How are field lines in a uniform magnetic field?
A. Curved
B. Parallel equidistant straight lines
C. Parallel but non-equidistant straight lines
D. Nothing can be said

Answer 1

Hint- We will first understand what a uniform magnetic field is and what is its definition. A uniform magnetic field is where the magnetic field lines are moving from the N to S pole of a magnet with a uniform division and they are going in a straight line.

Complete Step-by-Step solution:


Magnetic fields are unimaginable to expect to acquire with a solitary permanent magnet. As a matter of first importance, you should realize what attractive transition is, M-Flux is the quantity of magnetic field lines coming out of a magnet for every unit territory. On the off chance that the number is high the magnetic field is strong. If the number is less the magnetic field is frail.
Following are the properties of the magnetic field:
i. The magnetic field lines don't traverse one another.
ii. The magnetic field lines are consistently in a shut circle moving from the north pole toward the south pole.
iii. The course of the magnetic field is tangent to the field line.
iv. The strength of the field is always proportional to the density of the lines.
As per asked by the question- In a uniform magnetic field, the field lines are parallel equidistant straight lines.
Hence, option B is the correct option.

Note: To place this all in context, a uniform magnetic field is one where there is no gradient of magnetic field and the magnitude of the magnetic field is the same in the locale and subsequently the M-Flux is the same all over the place.
