Unipolar induction: a neglected topic in the teaching of electromagnetism
When a cylindrical magnet is rotated about its axis, electric fields develop on its surface which can be used to generate continuous currents. This effect is an example of electromagnetic induction, mechanical energy being converted into electrical energy, through the mediation of the magnetic field. It is suggested that the effect can be explained most simply in terms of the forces acting on c...
متن کاملA Quantitative Comparison of Unipolar and Augmented Unipolar Limb Leads
Goldberger has claimed that his augmented unipolar limb leads (aV) are identical except for a 50 per cent larger amplitude and interchangeable with Wilson's original V leads, but this claim was not supported by quantitative evidence. The advantage of larger amplitudes explains the increasing preference for the aV leads. A quantitative comparison between V and aV leads revealed such tremendous v...
متن کاملUnipolar Induction of a Magnetized Accretion Disk around a Black Hole
The structure and magnitude of the electromagnetic field produced by a rotating accretion disk around a black hole were determined. The disk matter is assumed to be a magnetized plasma with a frozenin poloidal magnetic field. The vacuum approximation is used outside the disk.
متن کاملBipolar and unipolar depression.
Since Kraepelin grouped affective disorders under the title of 'manic-depressive insanity', there has been controversy over whether the bipolar and unipolar entities within this are distinct affective disorders or whether they are merely two ends of an affective continuum. In order to bring some clarity and goal-posts to this argument, we define the criteria that must be fulfilled by diseases i...
متن کاملUnipolar spin diodes and transistors
Unipolar devices constructed from ferromagnetic semiconducting materials with variable magnetization direction are shown theoretically to behave very similarly to nonmagnetic bipolar devices such as the p − n diode and the bipolar (junction) transistor. Such devices may be applicable for magnetic sensing, nonvolatile memory, and reprogrammable logic.
