Question:
The charge which is a source of electric field but not of magnetic field is:
The charge which is a source of electric field but not of magnetic field is:
Show Hint
Remember, only moving charges create magnetic fields. A static charge produces only an electric field.
Updated On: Apr 23, 2025
- A charge moving in a straight line
- A charge static in space having zero speed
- A charge moving on helical path of pitch
- A charge oscillating with frequency \(v\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A stationary charge (zero speed) generates only an electric field, not a magnetic field. Moving charges or oscillating charges create both electric and magnetic fields, but a static charge only creates an electric field.

Uniform magnetic fields of different strengths $ B_1 $ and $ B_2 $, both normal to the plane of the paper, exist as shown in the figure. A charged particle of mass $ m $ and charge $ q $, at the interface at an instant, moves into region 2 with velocity $ v $ and returns to the interface. It continues to move into region 1 and finally reaches the interface. What is the displacement of the particle during this movement along the interface?
Consider the velocity of the particle to be normal to the magnetic field and $ B_2 > B_1 $.- JEE Main - 2025

- A proton is moving undeflected in a region of crossed electric and magnetic fields at a constant speed of \( 2 \times 10^5 \, \text{m/s} \). When the electric field is switched off, the proton moves along a circular path of radius 2 cm. The magnitude of electric field is \( x \times 10^4 \, \text{N/C} \). The value of \( x \) is \_\_\_\_\_. (Take the mass of the proton as \( 1.6 \times 10^{-27} \, \text{kg} \)).
