Explains how magnetic field strength changes with distance and how field direction is defined using the force on a north pole, including magnetic field lines from north-seeking to south-seeking poles. Introduces the motor effect, links current in a wire to magnetic field production, and describes solenoids, iron cores, electromagnets, and the rotation principle behind electric motors.","| Permanent and induced magnetism, magnetic fields and fields |  |\n| --- | --- |\n| The region around a magnet where a force acts on another magnet or magnetic material (iron, steel, cobalt and nickel) is the magnetic field. Magnetic forces are strongest at the poles of a magnet. Like poles repel and unlike poles attract. | A permanent magnet is always magnetic. An induced magnet is a material that becomes a magnet when placed in a magnetic field. When removed from the magnetic field, it loses most/all of its magnetism quickly |\n| The magnetic field gets weaker further from a magnet. | The direction of the magnetic field at a point is given by the direction of the force that would act on another north pole placed at that point. The direction of a magnetic field line is from the north (seeking) pole of a magnet to the\u003Cbr>south(seeking) pole of the magnet. |\n| | A magnetic compass contains a small bar magnet. The Earth has a magnetic field due to its core being magnetic. The compass needle points in the direction of the Earth’s magnetic field. The magnetic field pattern of a magnet can be plotted using a compass. |\n| The motor effect |  |\n| When a current flows through a wire a magnetic field is produced around the wire. The strength of the magnetic field depends on the current through the wire and the distance from\u003Cbr>| Shaping a wire to form a solenoid increases the strength of the magnetic field created by a current through the wire. The magnetic field inside a solenoid is strong and uniform. The magnetic field around a solenoid has a similar shape to that of a bar magnet. |\n| Adding an iron core increases the strength of the magnetic field of a solenoid. An electromagnet is a solenoid with an iron core. |  |\n| HIGHER TIER ONLY\u003Cbr>When a conductor carrying a current is placed in a magnetic field, then the magnet and the conductor exert a force on eachother. This is called the motor effect. | HT ONLY Fleming’s Left hand rule can be used to find the direction of the force:\u003Cbr>|\n| HT ONLY Use the equation F=BIl (Given on formula sheet) F = force (N)\u003Cbr>B = magnetic flux density (Tesla)\u003Cbr>I = current (A)\u003Cbr>L = length (m) | HT ONLY\u003Cbr>A coil of wire carrying a current in a magnetic field will rotate. This is the basis of an electric motor |","cbCaibvj0zPnt943","https://ap.wps.com/l/cbCaibvj0zPnt943","pdf",373790,1,"English","en",105,"# Permanent and induced magnetism\n## Magnetic fields and magnetic forces\n# Direction and mapping of magnetic fields\n## Compass and Earth’s magnetic field\n# The motor effect\n## Current, wires, and force\n## Solenoids and electromagnets\n## Fleming’s left-hand rule and F=BIl\n## Electric motors and rotation","[{\"question\":\"What is a magnetic field, and where are magnetic forces strongest?\",\"answer\":\"A magnetic field is the region around a magnet where a force acts on another magnet or magnetic material.
