Creating a Hysteresis Loop in MATLAB for Ferromagnets - Tips and Tricks

Click For Summary
SUMMARY

To create a continuous hysteresis loop in MATLAB for ferromagnets from scattered points, users can utilize the basic plotting function plot(x,y,'+') to visualize individual data points. For a more refined representation, it is recommended to separate the data into two sets: one for the forward direction and one for the backward direction, using the 'hold' function to overlay the plots. Additionally, incorporating directional indicators such as greater than (>) and less than (<) signs can enhance the clarity of the hysteresis representation.

PREREQUISITES
  • Familiarity with MATLAB plotting functions
  • Understanding of hysteresis loops in ferromagnetic materials
  • Basic knowledge of data manipulation in MATLAB
  • Experience with MATLAB's 'hold' function for overlaying plots
NEXT STEPS
  • Explore MATLAB's advanced plotting techniques for data visualization
  • Learn about data interpolation methods to create smoother curves
  • Investigate MATLAB's 'scatter' function for enhanced point representation
  • Study the principles of hysteresis in ferromagnetic materials for deeper insights
USEFUL FOR

This discussion is beneficial for MATLAB users, physicists, and engineers working with ferromagnetic materials, particularly those interested in visualizing and analyzing hysteresis loops.

Hallo,

If I have an hystersis loop (of ferromagnets) in form of scattered points in MATLAB what is the function or tool which i can use in order drew a continues hystersis curve(loop)?

Thanks,
Omri

plot(x,y,'+'); will plot the points in 2-d as + for each point.
 
You could also break it into two sets, one going forward, and one going backwards, and then plot both with the exact same settings (or using the 'hold' function). If you really wanted to get fancy, you could probably add a text greater than (>) sign and less than sign (<) to indicate the direction of the hysteresis.
