A strong magnetic field is applied on a stationary electron, then [BIT 1989; MP PMT 1995; CPMT 1999] A) The electron moves in the direction of the field. The electron moves in an opposite direction.

## Can you accelerate stationary charged particle in a magnetic field?

No magnetic force is exerted on a stationary charged particle. is the particle’s acceleration. This equation of motion was verified in a famous experiment carried out by the Cambridge physicist J.J. Thompson in 1897.

## Can you move a stationary charge by applying an electric field?

Yes. A changing magnetic field creates an electric field….

## What is the magnetic force on a positive charge in the stationary loop?

The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field. This implies that the magnetic force on a stationary charge or a charge moving parallel to the magnetic field is zero.

## How do magnetic fields affect moving charges?

Right Hand Rule: Magnetic fields exert forces on moving charges. The magnitude of the force is proportional to q, v, B, and the sine of the angle between v and B. If the particle velocity happens to be aligned parallel to the magnetic field, or is zero, the magnetic force will be zero.

## How do moving charges create magnetic field?

When an electrical charge is moving or an electric current passes through a wire, a circular magnetic field is created. This can be seen with iron shavings or filings on a card that will align in the magnetic field when a current is passed through a nearby wire….

## Do charges at rest produces electric field?

They are two aspects of the electromagnetic field. Charge at rest only produces electric field. Moving charge produces both electric field and magnetic field.

## Why is there no magnetic field outside the solenoid?

The magnetic field lines follow the longitudinal path of the solenoid inside, so they must go in the opposite direction outside of the solenoid so that the lines can form a loop. In order for the total number of field lines to be conserved, the field outside must go to zero as the solenoid gets longer.

## What is the magnetic field due to a solenoid?

A solenoid is a coil of wire with electric current flowing through it, giving it north and south magnetic poles and a magnetic field. Using more turns of wire in the coil or more current increases the strength of the solenoid’s magnetic field….

## Is magnetic field inside a solenoid is uniform?

A solenoid is a device that consists of a long conducting wire that is made up of many wire loops packed closely together. Inside the solenoid, the magnetic field lines are approximately uniform and parallel to one another, which implies that the magnetic field is also uniform inside the solenoid.

## How can you increase the magnetic field of a solenoid?

Strength of the magnetic field can be increased by:

1. increasing the current in the coil.
2. increasing the number of coils in the solenoid; and.
3. using a soft iron core within the solenoid.

## Why is the magnetic field stronger inside a solenoid than outside?

Answer. Current in solenoid produces astronger magnetic field inside thesolenoid than outside. The field lines in this region are parallel and closely spaced showing the field is highly uniform in strength and direction. Strength of the magnetic field can be increased by: increasing the current in the coil….

## What will be the magnetic field outside a long current carrying solenoid?

Note: For a very long solenoid the magnetic field outside will be zero and magnetic will be present only inside the solenoid.
