- Good spot. Perhaps they rounded it off to 3 significant figures.
- That's how you move in a circle, by constantly accelerating in a direction that is perpendicular to your velocity at that moment. Review circular m...
- In the page means the vector is pointing straight perpendicular into the page/screen. Similar for out.
- I need more understanding.

- Yes, they actually do decay over time.
- There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is...
- Applying high temperatures can cause a permanent magnet to lose some or all of its magnetic properties. This process is known as "demagnetization."...
- You can determine the north and south poles of a magnet by placing a magnet next to a compass and the compass will point toward the south pole of t...
- 1. Look it up. 2. Do that.
- Opposite poles attract each other but not the same poles because the density of the magnetic field lines is higher near the poles where the magneti...

Moving charges in a wire give rise to current, defined as charge divided by time. Consider a conducting wire of length L carrying current I in a magnetic field of strength Bthen the magnetic force is given by If the angle between the wire and the magnetic field is θ, then the magnitude of Fis F = I L B sinθ This equation gives the relationship betw...
Imagine two wires placed parallel to one another. The magnetic field at a distance r from an infinitely long wire carrying current I1is given by B1 = μo I1 / 2 π r When a second wire carrying current I2is brought closer and kept parallel to the first, it experiences a force given by F = I2 L B1 Or, F = μo I1 I2L / 2 π r The force per unit length is...
Magnets exert forces on each other and other metals. We can see this example in daily life. The capability of a magnet to attract objects comes from the principles of electromagnetism. According to electromagnetic theory, electrons’ motion around nuclei results in a current called a magnetic dipole. An ordinary bar magnet consists of many permanent...
