In what two ways is it possible to generate a higher voltage in a moving conductor?
The two ways of generating a higher voltage in a moving conductor are: 1. Increasing the speed of relative motion between the coil and the magnet 2. Increasing the strength of magnetic field.
Does electric field and electric field lines connected?
Yes. An electric field is represented by electric field lines. Electric field lines are a visual representation of the strength and direction of an electric field in a region of space. In the vicinity of any charge, there is an electric field and the strength of the electric field is proportional to the force that a test charge would experience if placed at the point. (That is a matter of definition of electric field.) Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. In the case of arrows, they are vector representations of the strength and direction of the electric field at the point in space where each arrow is drawn. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines. There is a small caveat. It is not only charge that can produce electric fields. An electric field can be produced by a changing magnetic field. This is technologically important (since electric motors work on this principle) and scientifically fascinating, requiring a somewhat more sophisticated aspect of electromagnetic theory, but ultimately the electric field or electric flux can be visualized with lines (or arrows) in a manner exactly as is done for stationary charges.
Electric field lines show the strength and what of an electric field?
Direction and electric flux density. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines.

What are two ways to produce electric fields electric fields are produced by charged particles or by changing magnetic fields?
One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.
What are some ways to increase the magnetic field strength?
Increase the size of the magnet. Increase the current passing through the wires (electromagnets) Increase the number of coils of the wire (electromagnets)

How can the strength of an electromagnet be increased?
More currents, or more loops.
Is media training an increasing occupation?
Yes, media training is an increasing occupation like many others these days. It's a good field to go into and it does involve a lot of money if you know your ways.
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
What are facts about electromagnetic fields?
An electromagnetic field is a physical field produced by electrically charged objects. The field can be viewed as the combination of an electric field and a magnetic field. The electromagnetic field may be viewed in two distinct ways: a continuous structure or a discrete structure.

How do radioactive rays behave in an electric and magnetic field?
That will depend on their electric charge: plus and minus charged rays will behave in opposite ways while uncharged rays will not be affected at all by the fields.
How do you increase current in electromagnet?
1. Increase the strength of the magnetic field. (More field lines to be cut by wire, therefore more voltage induced) 2. Move the magnet - or the wire - more quickly. (More field lines cut per second, therefore more voltage induced) 3. More coils in wire. (A single straight wire moved in a magnetic field will cut the lines once, but a coil of wire will cut the lines twice. More coils, more cutting, more induced voltage).
What are ways to increase friction?
1)increasing the roughness of the surface 2)increasing the mass of the object
What are some ways to increase the magnetic field strength?
