How does increasing the current increase the strength of the magnet?
Increasing the current in a wire creates a stronger magnetic field around it due to Ampère's law, which states that the magnetic field strength is directly proportional to the electric current flowing through the conductor. As the current increases, the magnetic field lines become denser and more concentrated, resulting in a stronger magnetic force. This principle is fundamental in electromagnets, where adjusting the current allows for control over the magnet's strength. Thus, higher current leads to a more powerful magnet.
How will you justify that ice and water and water vapour are the states of a substance and not substance?
Ice, water, and water vapor are all different states of the same substance, which is H2O or water molecules. These states represent different configurations of the molecules due to changes in temperature and pressure. They can interconvert between each other through the processes of freezing, melting, evaporation, and condensation.
How can you magnetize water?
SeeMagnetic purification apparatusUnited States Patent 6103113As an example of how to purify water from a river by precipitating the impurities with a magnetic particle containing flocculant and then filtering passing the water through a magnetic field
When a magnet is moved alongside a wiremwhat happens?
When a magnet is moved alongside a wire, it induces an electric current in the wire due to the phenomenon of electromagnetic induction. This occurs because the changing magnetic field around the wire generates an electromotive force (EMF) according to Faraday's law of electromagnetic induction. The direction of the induced current depends on the direction of the magnet's movement, as described by Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic flux.
What states of matter exist when a substance id freezing?
When a substance is freezing, it transitions from a liquid state to a solid state. During this process, both the liquid and solid states can coexist. This occurs at the freezing point, where molecules begin to arrange into a structured solid as energy is removed, while some molecules may still remain in the liquid form. Thus, the states of matter present during freezing are liquid and solid.
What if your penny sticks to magnet?
If a penny sticks to a magnet, it is likely a result of the penny being made of certain metals, such as zinc or steel, which are magnetic. Pennies minted after 1982 in the United States are made predominantly of zinc, which contains magnetic properties.
Does a us silver dollares stick to a magnet?
No, a US silver dollar does not stick to a magnet because silver is not a magnetic metal. United States silver dollars are made primarily of silver, which is a non-magnetic metal, so they will not be attracted to a magnet.
Is a modern United States penny magnetic?
Neither the original copper or the newer version copper-zinc penny is magnetic. The 1943 steel penny was the only penny effected by a magnet.
Example of natural magnet?
Magnetite is an example of a natural magnet. It is a type of iron ore that is naturally magnetic and can attract materials containing iron. Magnetite is commonly found in countries like Sweden, Russia, and the United States.
What determines the strength of a magnetic field?
factors on which magnetic field a bar magnet depends :- 1. pole strength of the magnet 2. medium in which the bar magnet is present(since the permittivity changes) factors on which external magnetic field(B) of a current carrying coil depends:- 1. the amount of current flowing through the conductor 2. the perpendicular distance of the point from the conductor. 3. medium in which the conductor is present(since the permittivity changes)

How many molecules in 2.1 mole?
2,1 mole of any substance contain 12,646 496 709(27).1023 molecules.
What are the Auroras in the upper atmosphere caused by?
Aurora are caused by energetic particles that emanate from the Sun, these collide with molecules in the upper atmosphere. The collision pushes the molecules into higher energy states and when the molecules fall back to lower states they emit photons.The Earth's magnetic field accelerates the solar particles and therefor the aurora are seen in a ring centered around the north and south magnetic poles.
How heat energy can change the states of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.

These states represent different configurations of the molecules due to changes in temperature and pressure. They can interconvert between each other through the processes of freezing, melting, evaporation, and condensation.
What happens if you suspend a bar magnet so it can go freely?
if the magnet has a low enough mass, and the string induces very little forces and friction on the magnet, it will act like a compass, the south end will point to the north pole and vice versus with north
