(i)
Name and state the rule to determine the direction of force experienced by a current carrying straight conductor placed in a uniform magnetic field which is perpendicular to it.
(ii)
An alpha particle while passing through a magnetic field gets projected towards north. In which direction will an electron project when it passes through the same magnetic field ?
(i)
What is a solenoid ?
(ii)
Draw the pattern of magnetic field lines of the magnetic field produced by a solenoid through which a steady current flows.
Marking-scheme solution
(a) i) • Fleming's left-hand rule
Stretch the thumb, forefinger and middle finger of your left hand such that they are mutually perpendicular. If the first finger points in the direction of magnetic field and the second finger in the direction of current, then the thumb will point in the direction of motion or the force acting on the conductor.
ii) South
OR
b) i) A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder.
