The cards Question Which two poles does every magnet have? Tap to flip Answer A north-seeking pole and a south-seeking pole. Question Do unlike magnetic poles attract or repel each other? Tap to flip Answer They attract. Question Do similar magnetic poles attract or repel each other? Tap to flip Answer They repel. Question Which pole of a magnet attracts a magnetic material? Tap to flip Answer Both: magnetic materials are attracted to north-seeking and south-seeking poles. Question Name the three magnetic metal elements. Tap to flip Answer Iron, cobalt and nickel. Question Are all metals magnetic? Tap to flip Answer No: of the elements, only iron, cobalt and nickel are magnetic. Question Why does the north-seeking pole of a magnet point towards the North Pole? Tap to flip Answer Because Earth has a magnetic field. Question What is a magnetic field? Tap to flip Answer A region where a magnetic material experiences a force. Question What is a plotting compass? Tap to flip Answer A small compass that can show the field of a magnet. Question What does the needle of a plotting compass do near a magnet? Tap to flip Answer It lines up with the magnet's magnetic field. Question What is a magnetic field line? Tap to flip Answer An imaginary line that shows the direction and shape of a magnetic field. Question A magnetic field line runs from which pole to which pole of a magnet? Tap to flip Answer From the north-seeking pole to the south-seeking pole. Question What do the arrows on magnetic field lines show? Tap to flip Answer The direction in which the north-seeking pole of another magnet would be forced. Question Can magnetic field lines cross over each other? Tap to flip Answer No: they do not cross over, and they are continuous. Question What is there around a wire when an electric current flows in it? Tap to flip Answer A magnetic field. Question Why is the field of a current-carrying coil stronger than that of a single wire? Tap to flip Answer The magnetic fields around each loop add together. Question In a coil of wire, what is a turn? Tap to flip Answer A single loop of wire. Question What is the core of an electromagnet? Tap to flip Answer The centre around which the wire is wound to make a coil. Question What three things are used to make an electromagnet? Tap to flip Answer A coil, a core and a power supply. Question Does a balloon with a static electric charge affect the magnet in a plotting compass? Tap to flip Answer No: a magnetic field is not the same as the electric field around a charged object. Question How does adding more turns of wire to the coil change an electromagnet's field? Tap to flip Answer It makes the magnetic field stronger. Question How does a greater current through the coil change an electromagnet's field? Tap to flip Answer It makes the magnetic field stronger. Question How does spacing the turns of wire more closely change an electromagnet's field? Tap to flip Answer It makes the magnetic field stronger. Question Why does a soft iron core make an electromagnet stronger? Tap to flip Answer The core becomes magnetised when the electromagnet is turned on. Question Will an electromagnet made from bare wire work if neighbouring turns touch? Tap to flip Answer No, it will not work. Question In an experiment, what is the independent variable? Tap to flip Answer The variable that the person doing the experiment changes. Question In an experiment, what is the dependent variable? Tap to flip Answer The variable that the person doing the experiment measures. Question What is a fair test? Tap to flip Answer An experiment in which the control variables are kept the same. Question Why is an electromagnet called a temporary magnet? Tap to flip Answer It loses its magnetism when the current stops flowing through it. Question How does an electromagnetic door lock unlock a door? Tap to flip Answer An electromagnet pulls a magnetic bolt. Question In an electric bell, what does the electromagnet do to make the bell ring? Tap to flip Answer It attracts and moves the striker so that it hits the bell. Question How does the striker of an electric bell spring back? Tap to flip Answer As the electromagnet moves the striker, it breaks its own circuit, letting the striker spring back. Question Which part of an electric motor is an electromagnet? Tap to flip Answer The spinning coil of wire. Question Should the coil of an electromagnet be made of insulated or uninsulated wire? Tap to flip Answer Insulated wire, so that the current in each turn adds to the strength of the electromagnet.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
