Practice CBSE Class 12 Magnetism and Matter in the app →A bar magnet is cut into two equal halves perpendicular to its length. Each half has:The angle between magnetic north and geographic north at a place is called:A bismuth bar near a strong magnet on the lab table is:Above the Curie temperature, a ferromagnetic material:A freely suspended bar magnet settles pointing:The tip of a magnet pointing to geographic north is its:Magnetic monopoles, according to the text:Cutting a bar magnet in half gives:Magnetic field lines of a bar magnet form:A bar magnet behaves like a magnetic:Substances repelled by a magnetic field are:Materials are classified by which quantity?Substances that are weakly magnetised in a field are:Substances that are strongly magnetised in a field are:A ferromagnet is divided internally into regions called:In an unmagnetised ferromagnet, the domains are:Applying a field makes the domains:Above a certain temperature, a ferromagnet becomes a:The Earth's magnetic field runs approximately from geographic:A bar magnet can be modelled as a large number of:The magnetic moment of a bar magnet equals that of an equivalent:Inside a diamagnetic material, the field is:Diamagnetism arises in atoms whose electrons have no net:Field lines of a bar magnet differ from an electric dipole's because they:The earth's magnetic field points approximately from geographic:A freely suspended bar magnet comes to rest pointing:A suspended magnet points one tip north; that tip is its:Bringing two north poles close together produces:Bringing a north pole near a south pole produces:Breaking a bar magnet into two halves gives:Isolated magnetic poles, called magnetic monopoles:Magnets can be made out of:The magnetic field lines of a bar magnet form:A bar magnet behaves in an external field like a:The angle between true north and the compass north is called:The declination is greater at:The angle a balanced needle makes with the horizontal is the:Another name for the angle of dip is:Declination, dip and the horizontal component are called the:Substances pushed away from a strong magnetic field are:Substances that get weakly magnetised in a field are:Substances that get strongly magnetised in a field are:Ferromagnets keeping their magnetisation afterwards are called:Alnico is an alloy of iron, aluminium, nickel, cobalt and:Above the Curie temperature a ferromagnet turns into:Substances holding ferromagnetism for a long time are:
