As with magnetic fields, people are attracted to those who have the traits that are missing in themselves. For example. someone who hates the spotlight () may be drawn to someone who loves attention.(A) 1. Why do many people think they and their friends have more in common? A. Because...
People with different interests and personalities cannot be friends. Disagree. Opposites attract each other, as with magnetic fields. This is because people always think their opposites have something they regard as missing in themselves. Hence, they are open to befriending someone who is less ...
many of these birds still navigated effectively. This indicated that the magnetic field is not the only factor involved in the homing pigeon's ability to navigate.Since then, scientists have found that pigeons can sense sounds that humans cannot hear, and that “sound fields" may also help the...

This indicated that the magnetic field is not the only factor involved in the homing pigeon’s ability to navigate. Since then, scientists have found that pigeons can sense sounds that humans cannot hear, and that “sound fields” may also help them navigate. A theory that birds have a ...
(磁铁), which would influence the magnetic field, on the back of pigeons. They found that this prevented some pigeons' ability from flying home. However, many of these birds still navigated effectively. This indicated that the magnetic field is not the only factor involved in the homing ...

There has been growing public concern about possible health effects of electric and magnetic fields produced by electricity generation, transmission and use. This concern is increasingly affecting electricity utilities; engineers cannot afford to ignore it. However, much of the concern is based on ...

eight poles must be better than two. But the reality is that multiple magnetic fields would fight each other. This could weaken the Earth's protective magnetic field by up to 90% during a polar flip.The Earth's magnetic field is what protects us from harmful space radiation which can damag...
