Antacids may be used: 1  To reduce the symptoms of acid reflux which may cause heartburn or inflammation of the gullet (oesophagitis) . 2  These conditions are sometimes called gastro-oesophageal reflux disease (GORD). 3  To relieve some of the symptoms caused by ulcers in the stomach and part of the gut called the duodenum.
Earthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.The field then creates the magnetosphere, which acts sort of like a force field, protecting the planet from the brunt of the sun's solar wind.arthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.
Magnetic Field Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. The magnetic field B is defined in terms of force on moving charge in the Lorentz force law. The interaction of magnetic field with charge leads to many practical applications. Magnetic field sources are essentially dipolar in nature, having a north and south magnetic pole. The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law F magnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).
