AQA Combined Science Physics Paper 2 Marking Scheme

01.1 iron and steel will be attracted (to the magnet) 1 AO1 6.7.1.1 aluminium, copper and tin will not be attracted (to the magnet) 1 allow 1 mark is one metal is in the incorrect list, but all the other four are correct if no other mark awarded allow 1 mark for iron and steel are magnetic 01.2 the paperclip would still be attracted to the magnet allow the paper clip becomes an induced magnet allow because the paper clip is a temporary magnet allow there is a magnetic field at the south pole 1 AO1 6.7.1.1 because of induced magnetism 1 01.3 weight = mass × gravitational field strength or W = mg do not accept gravity for gravitational field strength 1 AO1 6.5.1.3 01.4 1.0 g = 0.0010 kg allow 0.001 (kg) 1 AO2 6.5.1.3 weight of 1 paperclip = 0.0010 × 9.8 allow 0.0098 (N) allow correct substitution using incorrectly/not converted value of mass of paperclip 1 Force = 0.0098 x 20 = 0.196 (N) allow correct calculation using incorrectly/not converted value of mass of paperclip 1
