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?
The direction of magnetic field lines in the region left to the current carrying wire where the positive charge is moving will be perpendicularly inward the page according to the right thumb rule . The direction of movement of positive charge can be taken the direction of current . As the positive charge is moving toward left therefore it will be the direction of current , and magnetic field is perpendicular inward the paper so according to Fleming's left hand rule , force on positive charge will be toward the bottom of the page .
What is the direction of the net force on the particle due to the fields at the instant it enters?
A uniform magnetic field is directed out of the page. A charged particle, moving in the plane of the page, follows a clockwise spiral of decreasing radius as shown, then
A charged particle enters at right angles into a uniform magnetic field as shown :
What should be the nature of charge on the particle if it begins to move in a direction pointing vertically out of the page due to its interation with the magnetic field ?
A particle enters a magnetic field at right angles as shown.
The direction of force acting on the particle is into the page. The charged particle is a/an:
What is the direction of magnetic force on the positively charged particle q which is moving in the magnetic field of a long current carrying wire, as shown in the figure?
