Words and meanings to learn
magnetic field
the region around a magnet or a current-carrying wire where magnetic forces can be detected
current
the flow of electric charge through a conductor, typically measured in amperes (A)
solenoid
a coil of wire with many turns that produces a magnetic field when an electric current flows through it
electromagnet
a magnet created when a current flows through a solenoid, often with a core of magnetic material (like iron) to strengthen the magnetic field
concentric circle
objects or shapes that share the same center or axis; in the context of magnetic fields, concentric circles represent the magnetic field lines around a current-carrying wire

Samantha is an accomplished science educator whose current work centres on curriculum design and professional development, supporting teachers to deliver high-quality science education through evidence-informed approaches. She is a former Head of Chemistry and Sixth Form Tutor with extensive Key Stage 4 and 5 experience, and has worked as an AQA examiner, giving her valuable insight into assessment standards and what students need to succeed.
Samantha has written the complete KS4 Science curriculum, fully aligned with the AQA GCSE Science: Trilogy specification. Covering biology, chemistry and physics, the curriculum is carefully sequenced so that students build knowledge cumulatively and see clear connections between concepts across the three sciences. Drawing on her experience as an examiner and on research into effective teaching, she has designed it to embed retrieval practice, clear explanation, worked examples and the required practicals throughout, preparing students for the demands of the GCSE exams. Grounded in the realities of the classroom, the curriculum is rigorous for students and manageable for busy teachers.
In her spare time, Samantha enjoys playing the accordion with her local orchestra and has recently taken up cricket.
Making an electromagnet.
Magnetic field around a wire demo.
Large stiff wire, powerpack, clamp stands, card and plotting compasses.
Power packs, wire with stripped ends to make coils, iron cores (nails), paper clips, leads and croc clips (premade coils can help with timings).
