Magnetic Effect...

Inside the magnet, the direction of field lines is from

Find out the arrow or arrows which give the direction of conventional current flow.

Choose the correct option which describe the magnetic field produced by a current in a long, straight wire?

A positive charge is at rest in a uniform magnetic field directed to the right. What force does the positive charge feel, due to the magnetic field?

The diagram below shows a wire carrying current towards the top off the page. A positively charged particle is shown moving directly toward the left side of the page at a particular instant.
What is the direction of the force on the positively charged particle at the instant shown, due to the magnetic field produced by the current in the wire?

Below a negatively charged particle is pictured moving north east through a magnetic field that points straight up. What is the direction of the force on the negatively charged particle at the moment it is pictured?

A wire placed within a magnetic field has a current flowing in it as shown in the above figure. Identify the direction of the force exerted by the magnetic field on the wire.

The diagram below shows a positively charged particle moving toward the right and about to enter a magnetic field whose direction is shown by the blue arrows. What is the direction of the force on the positively charged particle (from our point of view) at the instant it enters the magnetic field?

In above shown figure, the direction of magnetic force and magnetic field is given then find out the direction of the particle velocity, v.

An electron enters with a velocity $$v$$ to the right in a magnetic field $$B$$, also to the right. What direction is the force $$F$$ on the electron?
