We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount of coils in an electromagnet gives a larger EMF. Variables- Independent: Length of wire‚ Number of Coils in magnet Dependent: EMF produced‚ Magnetic Field Strength

into two types: sheet metal drawing and wire‚ bar‚ and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire‚ bar‚ and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature‚ thus classified a cold working process‚ however it may be performed at elevated temperatures to hot work large wires‚ rods or hollow sections in order to reduce

[Answer: (a) 7.6 N m–1; (b) 5.3 N m–1] 2. A 1.5 m length of wire carrying 4.5 A of current is oriented horizontally. At that point on the Earth’s surface‚ the dip angle of the Earth’s magnetic field makes an angle of 38° to the wire.

out the amperage or the voltage‚ except one solution which had the chance to blow up our experiment. Some of the problems leading the experiment to not work were to make double wires in to single wires. This caused us to waste a lot of one’s time and get the wires tangled up. We didn’t have ladder to put up the wires and the insulators very high. During the first experiment (which did not work) the kohm resistor and the germanium diode were backwards. Also the earphone during experiment two were

Hell in a Cell is a professional wrestling cage-based match held in WWE (formerly World Wrestling Federation). It features a large roofed steel cage structure or "cell" which encloses the ring and ringside area. While similar to the steel cage match in profile and structure‚ unlike the steel cage match wherein exiting over the cage results in a win‚ only executing a pinfall or submission will result in a win. As in a steel cage match‚ disqualifications do not apply. The original Cell was 16 ft (4
