Questions about the Charged Particles in Fields poster

What’s on the Charged Particles in Fields poster?

Electric field against Magnetic field, side by side. Electric field: F = qE, along the field; Electric field: Does work on the charge; Electric field: Changes kinetic energy; Electric field: Parabolic path if entering perpendicular; Electric field: Used to accelerate; Magnetic field: F = Bqv, perpendicular to both; Magnetic field: Does no work; Magnetic field: Speed unchanged; Magnetic field: Circular path, r = mv/Bq; Magnetic field: Used to steer and select; A velocity selector uses both: only particles where qE = Bqv pass straight through, s…. The mass spectrometer and the cyclotron both work by combining these two behaviours.

Who is the Charged Particles in Fields poster for?

Charged Particles in Fields belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning electromagnetism can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Charged Particles in Fields poster?

Electric fields accelerate along the field. Magnetic fields curve without changing speed. A wall chart earns its place by being glanceable from where the work is happening, so Charged Particles in Fields belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Charged Particles in Fields?

AC Circuits, Capacitance and Circuit Basics sit alongside Charged Particles in Fields in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AC CircuitsCapacitanceCircuit Basics

Is the Charged Particles in Fields poster free to download and print?

Yes. Charged Particles in Fields downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Charged Particles in Fields poster print at?

Charged Particles in Fields is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Charged Particles in Fields loses nothing.Printing guide
