The cards Question What two poles do all magnets have? Tap to flip Answer A north-seeking pole and a south-seeking pole. Question What do unlike magnetic poles do to each other? Tap to flip Answer They attract each other. Question What do like magnetic poles do to each other? Tap to flip Answer They repel each other. Question Which three metal elements are magnetic? Tap to flip Answer Iron, cobalt and nickel. Question What is a magnetic material? Tap to flip Answer A material that is attracted to a magnet. Question Is steel a magnetic material? Tap to flip Answer Yes; alloys of iron, cobalt and nickel, such as steel, are magnetic. Question A north-seeking pole is attracted to which pole of the Earth? Tap to flip Answer Earth's magnetic North Pole. Question What is the needle of a compass? Tap to flip Answer A tiny magnet that turns freely to line up with the direction of a magnetic field. 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 What is there around a wire when there is an electric current in it? Tap to flip Answer A magnetic field. Question What is an electromagnet? Tap to flip Answer A magnet that can be turned on with an electric current, and turned off. Question The magnetic field of an electromagnet is similar to the field around what? Tap to flip Answer A bar magnet. Question What is soft iron? Tap to flip Answer Very pure iron that cannot be made into a permanent magnet. Question What is a turn of wire in a coil? Tap to flip Answer A single loop of wire in the coil. Question What is the coil of an electromagnet? Tap to flip Answer An insulated wire wound into the shape of a spring. Question With a current in a coil of wire, why is the field stronger than around a single wire? Tap to flip Answer The magnetic field around each loop adds together. Question What do error bars on a graph show? Tap to flip Answer The uncertainty of each measurement. Question Unlike a statically charged balloon, does an electromagnet attract small pieces of tissue paper? Tap to flip Answer No; a magnetic field is not the same as the electric field around a charged object. Question Why does a soft iron core increase the strength of an electromagnet? Tap to flip Answer It becomes magnetised when the electromagnet is turned on. Question How does winding the coil more tightly affect an electromagnet's magnetic field? Tap to flip Answer It makes the field stronger. Question How does a greater current through the coil affect an electromagnet's magnetic field? Tap to flip Answer It makes the field stronger. Question How is the strength of an electromagnet related to the current through it? Tap to flip Answer It is directly proportional to the current. Question If two variables are directly proportional, what happens to one when the other doubles? Tap to flip Answer It doubles too. Question Why is an electromagnet called a temporary magnet? Tap to flip Answer It loses its magnetism when current stops flowing through it. Question How does an electromagnetic door lock unlock a door? Tap to flip Answer Its electromagnet pulls a magnetic bolt. Question In an electric bell, what does the electromagnet do to the striker? Tap to flip Answer It attracts and moves the striker so it hits the bell. Question How does an electric bell let its striker spring back? Tap to flip Answer As the electromagnet moves the striker, it breaks its own circuit. Question What does an electric motor use a magnetic field to produce? Tap to flip Answer A force. Question What spinning part of a motor is an electromagnet? Tap to flip Answer Its spinning coil of wire. Question What pushes the spinning coil of a motor round when there is a current in it? Tap to flip Answer Other magnets around it. Question Why must the coil of an electromagnet be made of insulated wire? Tap to flip Answer So the current in each turn adds to the strength of the electromagnet. Question Why is the wire in a motor insulated? Tap to flip Answer So that the current flows around the coil. Question What is an electrical insulator? Tap to flip Answer A material that does not conduct electric current. Question What is an axle? Tap to flip Answer A rod at the centre of wheels and gears, around which they turn. Question In a motor kit, what is the yoke? Tap to flip Answer A U-shaped piece of iron that holds two magnets in place to create a uniform magnetic field. Question Why do the connections in a motor slide over each other? Tap to flip Answer To prevent the wires getting tangled. Question In a motor kit, what happens to the coil connections every half-turn? Tap to flip Answer They swap over, changing the direction of current through the coil. Question In a motor kit, how is each side of the coil at 90° to the field pushed every half-turn? Tap to flip Answer Alternately up, then down.

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.
