... Sometimes you need to change the voltage of the supply, either you need a higher or a lower voltage. You can do this by using a transformer, which consists of two coils, usually wrapped around each other to maximize the magnetic flux through the secondary coil. For example you need a transformer for ...

5.4 PPT - Magnetic Effects of Electric Currents
... Force on a current-carrying conductor in a B-field We now know the direction of the magnetic force acting on a current-carrying wire if it is in a magnetic field. The magnitude of the magnetic force F acting on a wire of length L and carrying a current of I in a magnetic field B is given by this f ...

... plasma core in the centre of the rf antenna. A magnetic field parallel to the cylinder axis is generated by four solenoids separated by 5 cm. A current of about 2 A produce a magnetic field of about 200 G on axis. Two extractors are placed perpendicular to the cylinder axis, i.e. perpendicular to th ...

... (a) Set up the image configuration, and calculate the potential in this region. What charges do you need, and where should they be located? (b) What is the force on q? (c) How much work did it take to bring q in from infinity? (d) (Extra Credit) Suppose the planes met at some angle other than 90o ; ...

Spontaneous Symmetry Breaking in Non Abelian Gauge Theories
... All that remains is to come up with dynamics for the gauge field alone, the analogue of the Maxwell Lagrangian − 14 (Fµν )2 . It turns out [10] that the key property of the field tensor that generalizes is that −ieFµν = [Dµ , Dν ]. In the non-abelian case have [Dµ , Dν ] = −ig(∂µ Aν − ∂ν Aµ − g 2 [A ...
