How you could use a wire and a battery to create a manetic field?

Any current will produce a magnetic field. If you let a current pass through the wire, you got your magnetic field.Note: If you connect the wire directly to the battery, without any resistance, you'll most likely destroy the battery, due to a short circuit.

What does a electromagnet create?
a magnetic field
How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
What happens to the magnetic field around a wire if you reverse the connection between the wire and the poles in a battery?
The magnetic field reverses polarity. North becomes South.
What does the Earth's molten core create?
Convection currents in the Earth's molten core are thought to be responsible for causing Earth's magnetic field.
Why does the induced current opposes the original cause in lenz's law?
The induced current creates a magnetic field that opposes the original cause of it because it is trying to resist the change in magnetic field in the area and the only way to do that is to create an equal and opposite magnetic field which leads to the induced current.
Remove positive battery terminal and car dies?
Yes it does. The alternator will only produce voltage if it has a battery supply. The battery power is used to create a magnetic field in the alternator. Spinning the magnetic field induces an electric field in the stator windings. Then the alternator can produce power to recharge the battery and maintain the electrical supply to the engine and ancilliary circuits.Take away the battery, no electrics, engine dies. Plus, it can also cause an electrical spike that could damage the computer.
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
Is electric charge moving in uniform motion produce both electric and manetic field?
Electric charge produces an electric field by just sitting there. It doesn't have to move. If it moves, it produces a magnetic field. It doesn't matter how the motion would be described.
When a magnetic field is used to create an electric current in a wire?
The magnetic field must be changing relative to the conductor (wire). So the wire could move through the field, or the field could move past the wire, or you could have a changing field (from an electromagnet with varying current).
Why is magnetic induction a vector quantity?
Magnetic field induction at a point is defined as the FORCE experienced by a unit north pole placed at that point. Since force is a vector quantity, manetic field induction also becomes a vector quantitiy.
Can a rotating masonry drill bit adjacent to a cable create a magnetic field and could it disrupt the electrical current within the cable?
No, a rotating masonry drill bit adjacent to a cable will not create a magnetic field and no it could not disrupt the electrical current within the cable .
What did Michael Faraday discover in 1831 that an electrical current could be produced by?
moveing a wire though a magnetic field
Can a moving electric charge create a magnetic field?
Yes. A spinning charge will create a magnetic field as will a moving charge.
What are the release dates for French Cuirassieurs Charging a Field Battery - 1897?
French Cuirassieurs Charging a Field Battery - 1897 was released on: USA: December 1897
Is magnetic flux the same as the magnetic feld?
magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.
