China Achieves New World Record with 42-Tesla Resistive Magnet Technology

China
has
set
a
new
world
benchmark
with
the
development
of
a
powerful
42-tesla
resistive
magnet.
The
country
has
broken
the
previous
41.4-tesla
record
maintained
by
the
United
States
since
2017.
The
breakthrough
was
achieved
on
September
22
by
the
High

Magnetic
Field
Laboratory
at
the
Hefei
Institutes
of
Physical
Science,
affiliated
with
the
Chinese
Academy
of
Sciences.
After
years
of
research
and
improvements
to
the
magnet’s
structure,
this
development
in
magnetic
field
technology
places
China
among
the
leaders
in
high-field
magnet
science,
offering
new
tools
for
scientific
and
material
research.

A
Major
Technological
Leap
in
Magnetism

The
42-tesla
resistive
magnet,
driven
by
a
power
source
of
32.3
MW,
is
a
proof
to
China’s
engineering
capabilities
in
this
field.
This
achievement
by
the
Hefei
lab
follows
their
earlier
accomplishment
with
the
world’s
strongest
hybrid
magnet,
which
reached
45.22
teslas
in
2022.
The
innovation
reflects
structural
and
production
advancements
made
over
nearly
four
years
of
continuous
effort.
It
resulted
in
the
output
being,
a
magnet
capable
of
maintaining
a
steady,
strong
magnetic
field.
This
enables
a
range
of
scientific
applications
that
rely
on
high
magnetic
fields
for

research
and
discovery.

Supporting
High-Level
Scientific
Research

The
new
resistive
magnet
provides
an
advanced
tool
for
scientific
investigations,
enabling
researchers
to
explore
materials
and
phenomena
at
extreme
magnetic
fields.
According
to
Guanli
Kaung,
academic
director
at
CHMFL,
magnetic
fields
of
this
strength
are
essential
for
investigating
fundamental
properties
of
materials,
often
leading
to
discoveries
in
physics
and
chemistry
that
have
real-world
applications.
High-field
magnets
are
critical
tools
for
researchers,
allowing
them
to
delve
into
questions
of
material
behaviour
and
atomic
interaction.

China’s
Position
in
Global
High
Magnetic
Field
Research

China
joins
the
ranks
of
five
other
nations,
including
France,
Japan,
the
Netherlands,
and
the
US,
in
hosting
dedicated
high-magnetic-field
research
labs.
With
several
Nobel
Prize-winning
breakthroughs
emerging
from
research
under
extreme
magnetic
conditions,
the
field
continues
to
be
a
focal
point
for
advanced
scientific
research.
China’s
latest
record
illustrates
its
commitment
to
expanding
the
potential
of
magnetic
science,
setting
a
high
bar
for
future
developments
in
the
field
