I am doing a science project on the effects of magnets on crickets. I was thinking of setting up a control and the experiment where the control has no magnetic field affecting the crickets and the experiment doesHowever, i do not know how to create a magnetic field. Can i just put a powerful magnet in the middle of the container?? Any suggestions?
magnetic fields are generated when you accelerate a charged particle, so you could use some sort of electromagnet, which means you could control the strength of the magnetic field by adjusting the strength of the electric current. a simple one to make is to coil a wire round an iron bar, such as a nail, and connect each end to a battery. the more coils and the stronger your battery, the stronger the magnetic field. *sorry, not accelerate, just move.
You are not not penalized for asking boring questions that no one answered. That does not increase your chance of being suspended. Neither do thumbs down or low BA percentages.
yea u can only get suspended for having probably 10 + violations unless they r rele bad but there is not set amount
The easiest way would be to use a permanent magnet. Buy one or pull one out a a speaker. You can also generate a magnetic field by running a current through a wire. In which case you need to wind it in a coil. However, the easiest way is to just use a more powerful magnet to begin with.
fpa06mr isn't correct. A magnetic field isn't created by the acceleration of a charged particle, but by the movement of a charged particle. If it's moving with no acceleration, it'll still create a magnetic field. So any current will create a magnetic field. So will any permanent magnet (a permanent magnet is just a block of material where a lot of the electrons are spinning in the same way. You can think fo this as a moving charge, ie a current. therefore it creates a magnetic field!)
