The method can include acquiring an electrical signal obtained from a magnetic element when supplying a first alternating current to a coil of a magnetic head and supplying a second current to the magnetic element. The magnetic head includes a first magnetic pole, a second magnetic pole, and a coil. The magnetic element is provided between the first magnetic pole and the second magnetic pole, and includes a first magnetic layer. The method can include detecting a time required for a change of an electrical resistance of the magnetic element based on a time when a polarity of the first alternating current is reversed based on the electrical signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Evaluation method of magnetic head and evaluation device of magnetic head","description":"According to one embodiment, an evaluation method of a magnetic head is disclosed.
