But a charge moving at an angle to the field experiences a sideways push known as the magnetic (Lorentz) force. Its magnitude depends on three quantities multiplied together: how much charge is moving, how fast it is going, and how strong the field is \u2014 scaled down by \\(\\sin(\\theta)\\), which accounts for the angle between the velocity and the field.<\/p>\n<p>The direction of the force is what makes magnetism unusual: it is always perpendicular to both the velocity of the particle and the magnetic field. You find it with the right-hand rule \u2014 point your fingers along the velocity, curl them toward the magnetic field, and your thumb gives the force direction for a positive charge. For a negative charge such as an electron, the direction is reversed.<\/p>\n<p>Because the force is always perpendicular to the velocity, it does no work on the particle: it cannot speed the particle up or slow it down. Instead, it continuously bends the path. A charge moving perpendicular to a uniform field travels in a circle; at an arbitrary angle it follows a helix, spiraling around the field lines. This is the principle behind particle accelerators, mass spectrometers, cyclotrons and the magnetic confinement of plasma in fusion reactors.<\/p>\n<p>For comparison, an electric field pushes a charge along the field lines regardless of its motion \u2014 see the <a href=\"https:\/\/wpcalc.com\/en\/physics\/electric-field-of-a-point-charge-calculator\/\">Point Charge Electric Field calculator<\/a>. The full Lorentz force combines both effects, \\( F = q(E + v \\times B) \\); this calculator covers only the magnetic term \\( qv \\times B \\).<\/p>\n<h2>Assumptions and limitations<\/h2>\n<ul>\n<li><strong>Only the magnetic part of the Lorentz force is computed.<\/strong> Any electric field present is ignored, as is the radiation a rapidly accelerating charge may emit.<\/li>\n<li><strong>The field is treated as uniform<\/strong> at the particle's location. In strongly non-uniform fields the force varies along the trajectory.<\/li>\n<li><strong>Relativistic effects are neglected.<\/strong> The formula \\( F = |q|vB\\sin(\\theta)\\) holds exactly for the coordinate speed at any velocity, but Newtonian trajectory analysis breaks down near the speed of light.<\/li>\n<li><strong>Only magnitudes are entered.<\/strong> The calculator returns the force magnitude; the sign of the charge merely reverses the force direction, so use the right-hand rule to find it.<\/li>\n<li><strong>Special angles:<\/strong> at \\(\\theta = 0^\\circ\\) or \\(180^\\circ\\) the particle moves parallel to the field and the force is zero; at \\(\\theta = 90^\\circ\\) the force is at its maximum, \\( F = |q|vB \\).<\/li>\n<\/ul>\n<h2>Typical field strengths for reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>Source<\/th>\n<th>Approximate B<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Earth's magnetic field at the surface<\/td>\n<td>25\u201365 \u00b5T<\/td>\n<\/tr>\n<tr>\n<td>Refrigerator magnet<\/td>\n<td>~5 mT<\/td>\n<\/tr>\n<tr>\n<td>Neodymium magnet near its pole<\/td>\n<td>~0.5 T<\/td>\n<\/tr>\n<tr>\n<td>MRI scanner<\/td>\n<td>1.5\u20133 T<\/td>\n<\/tr>\n<tr>\n<td>Strongest laboratory pulsed magnets<\/td>\n<td>up to ~100 T<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>With such a wide range of field strengths, unit choice matters \u2014 always check that the selected unit (Gauss, mT, \u00b5T or T) matches your data. 1 T = 10,000 G.
