マグネットの内部は、小さなマグネットがN極S極が反発し合うかたちで詰め

マグネットの内部は、小さなマグネットがN極S極が反発し合うかたちで詰め込まれていて、磁力の強い所と弱い所が交互にあります。そのため、素早く測定器具を動かしてしまうと、磁力の強い箇所を通り越して測定できない場合があるので、ゆっくり動かすようにします

Magnet inside was packed in small magnet will repel the N pole pole, have alternating weak and strong magnetic field. As a result, move slowly past the strong points of the magnetic force will move the measuring instrument quickly and there cannot be measured, so that the

The interior of the magnet, small magnet have been packed in a way that repel the N pole S pole, where strong force and weak where there are alternately. For this reason, and it will move the quick measurement equipment, because there is a case that can not be measured past the strong magnetic force point, so that you move slowly

The interior of the magnet, the magnet is packed in a small but very S N repels the pole, and the strong magnetic force is weak, there are alternately. Therefore, the measurement instrument to move quickly, so that a strong magnetic force can not be measured at the past, so as to move slowly.
