Animations

Magpylib can display the motion of objects along paths in the form of animations. The following example shows how to set up such an animation.

Hint

If your browser window opens, but your animation does not load, reload the page (ctrl+r in chrome).

Detailed information about how to tune animations can be found in the graphics documentation. Animations work best in the plotly backend. Avoid rendering too many frames.

import numpy as np
import magpylib as magpy

# create sensor with path
sensor=magpy.Sensor().rotate_from_angax(
    angle=35*np.sin(np.linspace(-4,4,36)),
    axis='y',
    anchor=(0,0,-.05),
    start=0,
)

# create magnet with path
magnet = magpy.magnet.Cuboid(
    dimension=(0.02,0.01,0.01),
    polarization=(0.3,0,0),
    position=(0,0,-.03)
).rotate_from_angax(
    angle=np.linspace(0,360,37),
    axis='z',
    start=0,
)

# display as animation - prefers plotly backend
magpy.show(sensor, magnet, animation=True, backend='plotly')
