Question

A charged particle is moving in a circle at right angles to a magnetic field. velocity of the charges particle is increased but the direction of its motion stays same, the circle will become larger in radius smaller in radius a spiral a helix The magnetic flux through a loop is defined as The field strength x the area x the sine of the angle that the normal to the loop makes with the plane of the loop. The field strength times the perpendicular velocity of the loop. A loop of wire is placed in a uniform magnetic field B. You will induce an emf, if the diameter of the loop is changed the orientation of the loop with respect to the field direction is changed the magnetic field is changed all of the above Solve any four of the following. Answers must include proper units. Express very large or very small numbers as powers of 10 A 2ohm, a 3 ohm and a 6ohm resistor are connected in parallel and placed across the terminals of a 12 volt battery. How many electrons will pass through the battery in one hour A 2. cm segment of a wire carrying 100 A is placed between the pole faces of a 5.00 Tesla magnet. Find the magnitude of the magnetic this segment of wire.

Explanation / Answer

8) a) larger in radius

because, r = m*v/(B*q)

9) a is the correct answer

magnetic flux through a loop = A*B*cos(theta) (here theta is the angle between normal to the loop and magnetic field)

10) d) all the above.

in all the three cases magnetic flux changes.so, emf will be induced.
