A. attracted by the magnet.B. unaffected by the magnet.C. repelled by the magnet.D. made into an induced magnet.
Dan has good ideas. Add to that: Depending on the axle/wheel arrangement, does it have grease fittings? Small trailer tires (with small axles) are going incredibly fast when being pulled 50 MPH. This generates loads of heat, and without adequate greasing (plenty often) they fry.that's why you see a lot of them sitting on the side of the road, waiting for the tow truck. Ease of use could be a factor. Another aspect is the tongue length load (the 'balance' overall). Axles placed too far forward create lift on the hitch which may pop off the ball under duress; too far back puts too much load on the towing vehicle, which may exceed vehicle recommendations. The receiver itself should be of the newer breed, with safety chains.all securely welded.
Get one that will do more than the job required. In other words don't buy one that is too lightweight. You can buy used trailers on Craigslist if you want to save some money over new. The trailers sold at home improvement stores are not designed for heavy use. Give careful consideration to your long term needs before you make the purchase. Good luck.
if the bar is stable then B if you spin the bar at a high rate of speed it creates magnetic field so then A or C trains in japan use compounds of aluminum and copper to produce magnetic fields
B - it heavily isn't affected. be conscious: truly, all issues impact and are stricken by technique of magnetic fields. inspite of the undeniable fact that, many products, copper and aluminum blanketed, do no longer exhibit something it really is seen to the interest. Copper also makes an awesome, even inspite of the undeniable fact that extreme priced, shunt for magnets.
B. unaffected by the magnet this is the correct answer, because : For A. to happen it should have material like iron in it to get attracted. For C. to happen it should be a magnet itself and Copper can't be a magnet (see why D is wrong) For D. It should be a material where as small magentic domains within the material can align themselves to become a magnet. Copper does not have this property. D can happen only for magentic materials (those that can be made into induced magent) but Copper is not such a material. So A,C,D are wrong. Hence the correct answer is B (Copper remaiins unaffected by magnet is true).
