Magnetic field

interested in discovering. Over the years, many scientists have made huge strides in the scientific world as to how magnets work. Magnets that repel one another can cause one of the magnets to levitate over the other. A magnet is an object with a magnetic field. A magnet appeals to any object containing iron. These objects are considered ferrous objects and may include pieces of iron, cobalt, nickel, and steel. The end of a magnet will always point in either the North or South direction. The end that

there a significant change in the fringe pattern between the two colours when the magnetic field is at different values. The Zeeman effect is when light from a gaseous light source travels through an external applied magnetic field, and spectral lines split into symmetrically distributed components around the position of the zero field (also known as the “parent” line). This was investigated by creating a magnetic field and observing the fringes produced by the light source through a lens and colour

called the Maglev standing for magnetic levitation. It uses opposite poles to repel train from the tracks so there is very little friction and it can move very fast. It is the fastest type of train.

The origin of Earth's magnetic field has not been discovered but it is thought to be made from the spinning of the iron and nickel and the core of earth, anyways earth has a magnetic field. It is constantly changing every

gives rise to a current that creates a magnetic field that opposes the original change in flux ”1 Eddy Currents: circular movements of electrons due to a changing flux passing through the metal Induction cooktops use electromagnetic induction to produce heat. Under the cooktop are electromagnetic coils (induction coils) with circular coils and a solenoid placed horizontally2 AC is passed through the coil, creating an oscillating magnetic field. The magnetic field lines aim towards the cooking surface

Being a metal, plutonium should technically be magnetic, however, all evidence and studies up to this point in time have shown the exact opposite. A team at Los Alamos National Laboratory (https://www.lanl.gov/) have found where this missing magnetism actually it. But there are plenty of metals that don’t stick to a magnet. Yes, that’s true, though ‘magnetic’ in this sense means something a little different. Metals that don’t stick to magnets are known as ‘non-ferrous metals’. Some of these metals

A magnet is anything with a magnetic field. Magnets attract ferrous objects like pieces of steel, iron, nickel and cobalt. They slightly attract liquid oxygen and other materials and they slightly repel water, carbon and boron. Magnets are made from a mineral called magnetite, one of earths rare minerals. Magnetite is a dark grey or black color and when in sunlight, it can have a tint of brown. Magnetite can be found in large amounts by beaches or shores. It is also known as lodestone. Magnetite

Plate tectonic convergence at a rate of about 4 mm/year between the Eurasian and African. Plates dominates the straits of Gibraltar (Argus et al., 1989). The stratigraphic evolution of the sediment drifts is therefore greatly influenced by both regional tectonics and ocean circulation (Medialdea et al., 2009; Lopes et al., 2006; Terrinha et al., 2009; Zitellini et al., 2009). Coring results from Expedition 339 showed that initial contourite formation started at about 4.5 to 4.2 Ma ago with more

wires produces a magnetic field. The magnet will only move if the magnetic field is strong enough. The wire carrying the electrical current behaves like a magnet. It either attracts or repels the magnet that is above it. If the direction of the magnetic field changes, then the direction of the electrical current changes. Magnetic field is formed in concentric circles around a current-carrying wire, laying the wire flat ensures that the strongest part of the wire’s magnetic field interacts with the

structural integrity monitoring system. Background Magnetostriction Magnetostriction is a property of ferromagnetic materials that exhibit a mechanical strain in response to an applied external magnetic field. This effect is a reversible exchange of energy between the mechanical and the magnetic form. Magnetostriction was first described in 1842 by James Joule after he observed that a sample of

the electric charge has an electric field. An electric field can only be created by a positive charge and destroyed by a negative charge(Brightstorm, 2010). According to Bob emery, owner of senior physics website, to generate electric power it requires motion between a magnetic field and a conductor. Attraction of a magnet is limited to certain boundaries this is called the magnetic field of a magnet (Makemegenius, 2013). An electric current in a magnetic field will experience a force, (HyperPhysics
