Why are both negative and positive voltages generated as the magnet passes through the coil?

In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.

How do rechargeable batteries work?
Click the link below A rechargeable battery is also known as an accumulator. It uses one or more electrochemical cells. During the charging process the cathode end which is the positive has negative electrons pushed through it mixing in the small chamber of the battery. The anode has positive electrons come in. The positive and negative electrons are combined and mixed inside and are released from metal to metal contact and are then used as electricity.
What is the purpose of a phase-shift network in a Wien bridge oscillator?
A Wien bridge oscillator produces sine waves. In order for the sine waves to maintain a steady amplitude, a positive feedback system is used with some sort of control to limit gain. In order for the positive feedback system to work, the waves being "fed back" to the amplifier have to be in phase with the waves being generated. Thus, you need a phase shift network to ensure that the phases of the waves match, which in the case of a positive feedback system means that the generated waves need to go through a 360o phase shift during the feedback process.
What is the difference between a transmission grid and an electricity grid?
The terms transmission grid and electrical grid are somewhat interchangeable. The electrical grid, or power grid, is the network used to get electric power from where it is generated to all the places that use it. The one difference might be that a transmission line or grid might be thought of as the network of high voltage long distance lines. These are used to move large amounts of power with minimal loss through the use of extremely high voltages. These long distance lines connect generation facilities with substations, and it is at the substation that the voltages are stepped down, and that power is then put on the electrical grid.

The effect of internet on modern mass media society?
the Internet is both negative and positive, positive in the way that you can more easily get information, talk to your friends who are located on the other side of the planet, and more. negative in the way of hackers, rippers etc -Spownkie
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
Does energy flow through the negative or positive of a battery?
Negative side
Is the direction of current through a battery always from negative to positive on the terminals?

What is the solution to the equation -n equals 7?
- n = 7multiply through by, - 1- 1(- n = 7)a negative times a negative is positive ( and, of course, a negative time a positive is negative )n = - 7======check- (- 7) = 7( negative times negative = positive )7 = 7----------checks
What electricity travels through?
electricity can travel through anything with a positive and negative electrical charge
What is negative selection of immunology?
Immunology relies on both negative selection and positive selection. Negative selection, or non resultant, provides for discounting a method of treatment. Positive selection, or improvement can at times be found by elimination through negative selection.
