A magnetic field can be represented by lines called the lines of magnetic induction. It also expresses the strength of the mangetic field and it is a vector quantity. In a magentic field, the magnitude of magentic induction is equal to the magnetic flux per unit area at that point.

The unit of magnetic flux is called the weber (symbol Wb). As magnetic induction is equal to the magentic flux per unit area, the SI unit of magnetic induction is weber/metre^2, i.e, Wb/m^2. This unit is also called the tesla (symbol T0


Bio Savart Law

Consider a small element of length dl, of a conductor carrying a current I. Let P be any point at a distance r from the centre of the element along a line making an angle θ with the element. Then, according to this law, the magnetic induction dB at the point P due to the current element dl is given by

dB α I(dl)sinθ/r²

dB = K*I(dl)sinθ/r²

where K is a constant of proportionality whose value depends upon the system of units.

In the SI sytem, K for vacuum or air is written as Mu/4Pi and its value comes out to be 10^(-7) Wb/Am.

Magnetic induction is vector quantity and its direction can be determined by using the right hand rule.

JEE question 2007 Part I

A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder oflarger radius. Both the cylinders are initially electrically neutral.

(A) A potential difference appears between the two cylinders when a charge density is given to theinner cylinder
(B) A potential difference appears between the two cylinders when a charge density is given to theouter cylinder
(C) No potential difference appears between the two cylinders when a uniform line charge is keptalong the axis of the cylinders
(D) No potential difference appears between the two cylinders when same charge density is given toboth the cylinders

Sol: Ans [A]

Potential is constant inside cell due to charge on cell. To create potential difference charge must be given on inner cell.
-----------------------
JEE 2007 Paper II
Statement - 1

A vertical iron rod has coil of wire wound over it at the bottom end. An alternating current flows in the coil. A conducting ring that can float on the rod is above the coil at a certain height above the coil.

Because

Statement - 2

In the above situation, a current is induced in the ring which interacts with the horizontal component of the magnetic field to produce an average force in the upward direction.

(A) Statement – 1 is True, Statement – 2 is True; Statement – 2 is a correct explanation for statement – 1
(B) Statement – 1 is True, Statement – 2 is True; Statement – 2 is Not a correct explanation for Statement – 1.
(C) Statement – 1 is True, Statement – 2 is False
(D) Statement – 1 is False, Statement – 2 is True

Solution; (A)

Both statements are correct

The magnetic field on the ring has two components. The horizontal component contributes to up upward vertical force to balance the weight of the ring and allows it to stay at that place.

JEE Question 2007 paper I

In the options given below, let E(A,B)X denote the rest mass energy of a nucleus of material X and E(n)of a neutron. The correct option is
(A)E(236,92)U > E(137,53)I + E(97,39)Y + 2E(n)
(B)E(236,92)U < E(137,53)I + E(97,39)Y + 2E(n)
(C)E(236,92)U < E(140,56)Ba + E(94,36)Kr + 2E(n)
(D)E(236,92)U = E(140,56)Ba + E(94,36)Kr + 2E(n)

Sol: Ans [A]
(236,92)U breaks into smaller atoms and gives out energy.
