Why can't AC electricity be used to make an electromagnet?

In an electromagnet, the negative side of the coil is said to "emit" the magnetic field lines- it is the north pole of the electromagnet. However, in alternating current, the energized wire alternates between positive and negative. As a result, a conventional electromagnet running on alternating current would constantly be undergoing a reversal of the poles.


How Can a body moving with certain velocity in the direction of east have acceleration in the direction of west?

Is north negative?

North/south and negative/positive have nothing to do with each other.


Is a positive number minus a negative number equal to a negative number?

No it is a positive number, because there are two negative signs you cancel them. For example: 9-(-4)=13 Since there is a parenthesis between both signs (parenthesis means to multiply) you multiply. Negative X Negative = Positive; then the -4 becomes positive and finally you just add. Very complex isn't it. Think about it like this. Say you're in a car on a North-South road. North is positive, and South is negative. If you're a positive number, then point your car North, if a negative, point your car South. Now if you are to be added, then drive forward, and if you are to be subtracted, then put in reverse and drive backward. So in the above example, start at 9 miles North of a reference point (mile zero). Then you are negative 4, so point the car South, but since you are subtracting, drive in reverse for 4 miles (you will be moving toward the North, which is in the positive direction), and arrive 13 miles North of the reference point (positive 13). Hope this helps.

Do positive and negative magnets attract or positive and positive or negative and negative?

polar opposites attract. that's where the phrase "opposites attract" comes from.AnswerThere are no such things as 'positive' or 'negative' magnets, other than in the minds of magnetic therapists who seem to have very little scientific knowledge of magnetism! Magnetic poles, not magnets, are named after the directions in which the point when freely suspended -i.e. north and south.
