What else can I help you with?
Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.
Compare and contrast magnetism and gravity?
Gravitational fields and electromagnetic fields are different in that Gravitaional fields are dependent on the masses of objects and the electromagnetic field depends on the charges of objects.
How opposite charges or poles respond?
Opposite charges or poles attract each other due to the presence of a potential energy that decreases as the charges move closer together. This attraction is governed by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Can magnetic fields harm the body?
No. Look at the MRI, which generates enormous magnetic fields. It does not hurt the body. Even if you look at the iron in the blood, that iron is not ferromagnetic because it is distributed extremely finely, and iron needs to be in bulk form to be ferromagnetic.Another Answer:Sometimes. Large rapidly oscillating magnetic fields can cause extensive bodily damage. This damage is exactly similar to electromagnetic radiation damage received by exposure to gamma, x, and ultra violet radiation. Simply put magnetic fields by themselves are relatively harmless, but when used to induce electrical currents or chemical reactions, they can be moderately dangerous.As with practically everything, magnetic fields do have the potential to harm the human body, but it depends on the degree.Consider the extreme example: All materials have the property known as diamagnetism, which is basically caused by atoms creating a repulsive magnetic field to oppose an external magnetic field. Given a strong enough external magnetic field, this effect could rip apart the atoms in the body. This situation is unrealistic, but an example of a harmful effect nonetheless.As far as reality is concerned, there is an ongoing debate about whether magnetic fields can be harmful. There is evidence, but it's hardly conclusive. To learn all about the claims, evidence, studies, and conclusions, see the related link below.
How does the magnetic field affect magma?
Magnetic fields can influence the movement and alignment of magnetic minerals in magma, which can affect the cooling and solidification process. This can result in the formation of magnetic anomalies in the Earth's crust that can be used to study geological processes.
What allows matter to look bigger?
Larger magnetic fields.
What do the fields around two current wires look like?
See the related link Electro Magnetic Fields for a picture.
Only some currents are able to produce magnetic fields?
No. Any current produces a magnetic field. Look at Maxwell's equations.

Do opposite charges attract each other?
If the atoms have opposite charges (positive to negative) they will attract. If the atoms have the same charges (positive to positive or negative to negative) then they will repel. You can look at the Law of Electric Charges to get more information on this.
How does the magnetic field affect magma?
Magnetic fields can influence the movement and alignment of magnetic minerals in magma, which can affect the cooling and solidification process. This can result in the formation of magnetic anomalies in the Earth's crust that can be used to study geological processes.
What is an iron filing?
Iron filings are small shavings or particles of iron that are often used in experiments to visualize magnetic fields. They align themselves along the magnetic field lines when a magnet is placed near them, making the magnetic field visible.
What do magnetic field lines look like when two magnets repel each other?
When two magnets repel each other, the magnetic field lines will curve away from each other, showing a pattern of lines that do not intersect and point in opposite directions.
