Drag the bar magnet from left to right through the top coil, then repeat the same process after switching the polarity of the magnet. Fred swings a sheet of copper in pendulum fashion between the poles of a strong magnet. The sheet slows in entering the magnetic field because.Suppose we release a copper bar above a permanent magnet, what will happen to the subsequent motion of the bar?since copper is a good conductor, I think that eddy current once again exists in the copper bar, causing it to move slower. Is the phenomenon the same as the first experiment?Copper Bars are the easiest of metal Ores to craft in the Furnace. They are used in a wide variety of crafting projects.The copper bar will "feel" the magnetic field as it is moved through it toward the magnet. This will induce a voltage and cause current flow in the copper bar. The bar won't "shock" anyone, but the simple act of moving it through a magnetic field causes induction (or induces a voltage).B. attracted by the magnet. C. repelled by the magnet.

Mass of an object is 20 kg find its weight on the earth what will be it weight when measured on the surface of the moon??? for the same mass of two different substance greater the density , the _____is the volume.A bar magnet is a permanent magnet. This means that its magnetism is there all the time and cannot be turned on or off. A bar magnet has two magnetic if you bring two north poles together, or two south poles together, they repel and the magnets push each other away.

Pushing a bar magnet into a coil of wire can generate a larger current. Diamagnetism opposes the direction of an applied magnetic field. For example, if you held the north pole of a magnet near a strongly diamagnetic substance, this substance would be pushed away by the magnet.1. For a bar magnet, the magnetic field lines point a. towards the South pole. b. towards the North pole. c. always towards the magnet. d. always A 0.190 kg piece of copper is heated and fashioned into a bracelet. The amount of energy transferred as heat to the copper is 6.62 x 10^4 J. If the...B. repelled by the magnet. C. made into an induced magnet. These electric eddy currents push the magnet away from the copper bar. Magnetism and electricity are related and the interaction between the copper and a magnet is used in power plants to generate the electricity that we use every day....used to measure magnetic fields is made with a copper bar of thickness 2.50 _m . The conduction electron density of copper is 8.47×1028 m_3. Part A If the current in the bar is 440 mA , find the perpendicular magnetic field present when the Hall potential difference is 2.0 V . Express your...If a bar of copper is brought near a magnet, the copper barwill be (a) attracted by themagnet (c) repelled by the magnet (b) unaffected by themagnet (d)made into an induced magnet

First 3 answers are unsuitable. The act of bringing the magnet near copper will affect the copper, it will induce an electrical present in the copper (an eddy present). The eddy present will create a magnetic box that repells the magnetic box whilst the eddy present is flowing. This present will prevent when the magnetic box stops changing (when the magnet stops moving) however another eddy present will be brought on when the magnet is moved away again. The 2nd eddy current will be precisely opposite the first one if the magnet motion is exactly the reverse of it's first motion.

The magnitude of this eddy current will depend on the energy of the magnetic box and the pace at which the magnetic field adjustments. It additionally is determined by the temperature of the copper. If the copper is cooled to near absolute zero, it becomes a superconductor (I'm no longer certain what the superconducting transition temperature is however maximum metals transform superconductors down near 0K) and that will alternate the interaction with the magnet (the magnet will be repelled much more strongly).

If you need to see a demonstration of the sensible results, get a good sturdy magnet (NdFeB would be a good selection) and a short duration of copper tubing/pipe, say 1 foot lengthy. Drop the magnet through the pipe and see how lengthy it takes to fall. Drop a marble or a rock or a piece of copper or the rest that is now not magnetic via the pipe and spot how lengthy that takes to fall.

If you overlook the transients and look best at steady state... the first Three answers are right (neatly, type of, right, some of their "facts" are incorrect). Zinc is NOT magnetic. Fe, Ni, Co and (I consider) Gd are magnetic.
