Magnetic field and choices
A magnetic field of 1 t causes a proton beam of 2 ma to move in a circle with a radius of 01 m assume that the magnetic field is perpendicular to the plane that the circle is located on 30. Correct answer choice is: b outer core explanation: the earth's magnetic field diverts most of the solar radiation, whose charged particles can gradually reduce the ozonosphere that protects the planet from harmful actinic radiation. -there is a magnetic force acting on it (note the magnetic field is an external field, created by a permanent magnet or by other currents it is not the field of the current i in the wire) how we determine the force on a current carrying wire.
Others believe the choices were purely random the torque τ on a small magnet is proportional both to the applied magnetic field and to the magnetic moment m of . In an ac generator, a coil with n turns of wire spins in a magnetic field of the following choices, which will not cause an increase in the emf generated. The direction of the force on a current-carrying wire placed in a magnetic field depends on a the direction of the current b the direction of the field c the direction of current as well as field d neither the direction of current nor the direction of field 15. Alnico cow magnets this standard alnico cow magnet has a magnetic pole on each end, and is perfect for a 3d demonstration of magnetic fields, similar to that produced by the earth.
Form magnetic fieldit also shows four choices for the direction of that field (a) rank the choices according to the magnitude of the electric potential. To see a list of links to emf meters and instruments and emf-shielding products that oram to measure magnetic fields, you have a choice of purchasing single-axis . Strong magnetic field emissions (depending on how much electric current is flowing) and electric field emissions can make the nearby area hazardous to occupy, especially for long periods shielding is certainly possible, but the shield must not hamper quick and easy access to the controls inside the box.

You might expect turtles that live near each other or in similar environments would be genetically similar but new research shows that magnetic fields actually have more to do with genetic likeness. If the magnetic flux through a loop of wire changes for any reason either by changing the area, a, of the loop or the field, b, through the loop. To brake the train, the electromagnets are switched on, creating a magnetic field that induces eddy currents in the metal rails passing beneath them in the figure, which of the choices correctly represents the eddy currents induced in the rails.
