The figure shows a uniform, 3.0 T magnetic field that is normal to the plane of a conducting, circular loop with a resistance of 1.5 Omega and a radius of 0.024 m. The magnetic field is directed out of the paper as shown . Note: The area of the non-circular portion of the wire is considered negligible compared to that of the circular loop. What is the magnitude of the average induced emf in the loop if the magnitude of the magnetic field is doubled in 0.4 s?

A square loop is carrying a steady current I and the magnitude of its magnetic dipole moment is m.If this square loop is changed to a circular loop and it carries the same current the magnitude of the magnetic dipole moment of circular loop will be

A conducting circular loop is placed in a magnetic field of strength 0.04 T, such that the plane of the loop is perpendicular to the magnetic field. If the radius of the loop begins to shrink at a constant rate of 0.5 mm // s , then calculate the emf induced in the loop when its radius is 1.5 cm.

A square loop is carrying a steady current I and the magnitude of its magnetic dipole moment is m. if this square loop is changed to a circular loop and it carries the current, the magnitude of the magnetic dipole moment of circular loop will be :

Assertion A conducting loop is rotated in a uniform magnetic field with constant angular velocity omega as shown in figure. At time t = 0, plane of the loop is perpendicular to the magnetic field. Induced emf produced in the loop is maximum when plane of loop is parallel to magnetic field. Reason When plane of loop is parallel to magnetic field, then magnetic flux passing through the loop is zero.

A rectangular wire loop with length a and width b lies in the xy-plane as shown. Within the loop, there is a time dependent magnetic field given by vecB = c[(x cos omega t)hati+ (y sin omega t)hatk] . Here , c and omega are constants. The magnitude of emf induced in the loop as function of time is

Answer the following quesitons : (a) A closed conducting loop moves normal to the electric fieldd between the plates of a large capacitor. Is a current induced in the loop when it is (i) wholly inside the capacitor (ii) partially outside the plates of capacitor. Electric field is normal to the plane of the loop. (b) A rectangular loop and a circular loop are moving out of a uniform magnetic field region to a field free region with a constant velocity, Fig. In which loop do you expact the induced e.m.f. to be constant during the passage out of the field region, the field is normal to the loops ? (c ) Predict the polarity of the capacitor in the situation described by Fig.

A metallic loop is placed in a nonuiform magnetic field. Will an emf be induced in the loop?
