What is better for lifting heavy metal objects eletromagnet or permanet magnet?
permanet object
Does a magnetic field strengthen on weekend as you move away from the eletromagnet?
The magnetic field becomes weaker as you move away from the electromagnetic source.
The polarity of an eletromagnet is determined by the?
the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.
How is the magnetic field of an eletromagnet controlled?
The intensity of the magnetic field (measured in Teslas) produced by an electromagnet is directly proportional to the current (measured in Amperes) passing through it's coil windings. Therefore, as long as other variables remain constant, one can vary the intensity of the magnetic field by varying the current. Specifically, the intensity of the magnetic field will vary by the same factor as the current, so if the current is halved, the intensity of the magnetic field will also be halved; and if the current is tripled, the intensity of the magnetic field will also be tripled.
How do tosters work?
they just work they just work,work,work
Who invented the first eletromagnet?
Ugliness

What two things are 0.5 inches?
a oreo cookie and a small eletromagnet
What is better for lifting heavy metal objects eletromagnet or permanet magnet?
permanet object
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
Is a electromagnet with a six volt lantern battery really powerful or not?

What is a eletromagnet produced by?
I believe that it's spelled electromagnet. An electromagnet is produced by electricity flowing through a wire wrapped around a needle 30 or more times.
The polarity of an eletromagnet is determined by the?
the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.
How big is an eletromagnet?
An electromagnet can be any size from a few millimetres (magnetic tape or computer hard disc read/write heads) to several metres (industrial uses such as scrap yards for lifting steel, or research such as parts in particle accelerators and fusion reactors). The only limit to the upper size would be available materials and manufacturing technology.
How did African slaves get education?
They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.
