If the Earth were to lose its magnetic field, things would get a lot more interesting. We'd get a lot more ionizing radiation at the surface, which would result in more mutations (and more deaths).

What do you have to add to a compass to make it in line with the earths magnetic field?
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
Convection in the What creates earths magnetic filed?
Earth's molten outer core rotates. That outer core is made up mostly of molten iron. The movement of the molten iron produces the magnetic field.When currents in the outer core force the solid inner core to spin at a slightly faster rate than the rest of the planet causes the Earth to have a magnetic field.
How a starter solenoid works?
When the car is started, voltage is sent from the battery to the solenoid. The pull-in coil is capable of drawing a lot of current and generating a large magnetic field, and is the primary drain on the battery. This creates the magnetic force that draws the plunger into the core and completes the circuit between the terminals of the battery. The movement of the plunger causes the starter's drive gear to move into mesh with the flywheel ring gear. This is what causes the motor to turn. The hold-in coil generates a much weaker magnetic field and holds the plunger in place. This saves battery power and reserves most of the battery's life for starting the car.
What happens when you turn the ignition switch to accessory?
You turn on power to the accesories, ie radio, power outlet, etc.
What happens if you don't turn a car over to the repo man?
they will repo it
What happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.

What happens to the compass needle when you place it in the wire loop when the circuit was turn on?
it point same way as magnetic field
How can you turn off a magnetic field by a current?
If the magnetic field is caused only by a current, you can turn the current off.If you have another magnetic field, for example due to a permanent magnet, with a current you can create a magnetic field that counters the first one. But that will only work in certain regions in space; you can't cancel such a magnetic field everywhere in space.
How could you turn off a solenoids magnetic field?
only heskey can do this
How do electric generators produce a current?
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
Why doesn't a transformer work only on a DC supplyand not in ac supply?
A transformer doesn' t work with DC current because voltage is induced in the output winding of the transformer when a magnetic field passes through the coils of this winding. This happens with AC current because the magnetic field is continually expanding and contracting. With a DC current the magnetic field is unchanging other than when you first turn it on. Since the magnetic field is not moving it is not moving through the windings and no voltage is produced.
Loops of wire that turn in the magnetic field of an armature create?
alternating current
Loops of wire that turn in the magnetic field of an armature create current?
alternating
How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
How does coiling a wire affect the magnetic field generated an electromagnet?
Coiling a wire increases the magnetic field of an electromagnet because the magnetic field around a wire is circular and perpendicular to the wire. Each turn of the wire reinforces the field of the one next to it. The magnet field is strengthened. (I was in A+, too ;) ) - Dawn Ayers
