MCQ
Quantity that is not affected by magnetic field is:
- AMoving charge
- BChange in magnetic flux
- CCurrent flowing in conductor
- ✓Stationary charge
✓
Answer
Correct option: D.
Stationary charge
Magnetic field is the magnetic effect of electric currents andmagnetic materials.
The magnetic field at any given point is specified by both a direction and a magnitude $($or strength$)$; as such it is represented by a vector field.
As magnetic field has both magnitude as well as direction so it is a vector quantity.When charges are stationary, their electric fields do not affect magnets.
But, when charges move, they produce magnetic fields that exert forces on other magnets.
When there is relative motion, a connection between electric and magnetic fields emerges$-$each affects the other.
Quantity that is not affected by magnetic field is Stationary charge.
