    symbol ∇. Del may denote the gradient (locally steepest slope)‚ the divergence of a vector field‚ or the curl (rotation) of a vector field. The symbol ∇ can be interpreted as a vector of partial derivative operators‚ and its three possible meanings—gradient‚ divergence‚ and curl—can be formally viewed as the product of scalars‚ dot product‚ and cross product‚ respectively‚ of the del "operator" with the field. A. GRADIENT If a scalar function ‚ ‚ is continuously differentiable with respect to its

    SUMMARY Magnetic levitation is the process of levitating an object by exploiting magnetic fields. If the magnetic force of attraction is used‚ it is known as magnetic suspension. If magnetic repulsion is used‚ it is known as magnetic levitation. In the past‚ magnetic levitation was attempted by using permanent magnets. Earnshaw’s theorem however‚ proves that this is mathematically impossible. There exists no arrangement of static magnets of charges that can stably levitate an object. There

    A.C current meters Introduction An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A)‚ hence the name. Neither type of basic dc PMMC meter movement will correctly indicate an alternating current. There are‚ however‚ four basic types of meter movement that will indicate ac values:- Thermocouple Hot wire Electrodynamometer Iron-vane Electrodynamic ammeters An electrodynamic meter uses an electromagnet instead

    a) Derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries a current I. Your derivation should include the direction of the magnetic field with respect to the direction of current flow. Verify your expression by using the experimental results obtained. If your results do not show the expected relationship‚ explain why. In order to derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries

    Working When a current carrying conductor is placed in a magnetic field‚ it experiences a force and tends to move in the direction as per Fleming’s left hand rule. Fleming left hand rule: If the first and the second finger and the thumb of the left hand are held so that they are at right angle to each other‚ then the thumb shows the direction of the force on the conductor‚ the first finger points towards the direction of the magnetic field and the second finger shows the direction of the current in
