• # Abstract

This paper provides a method for judging growth or decay of the magnetic field of pulsar by using pulse period 𝑃, or frequency 𝑣, and its first and second derivatives $\dot{P}$, $\ddot{P}$ or $\dot{v}$, $\ddot{v}$. The author uses this method to judge the growth or decay of the magnetic field of Crab pulsar. The judged result for Crab pulsar is that the magnetic field of Crab pulsar is growing now, but it is not decaying. The result corresponds with the actual case of Crab pulsar.

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
